Best ResponseYou've already chosen the best response.03,10 3,10 6,10 6,10 My son said B

hartnn

Best ResponseYou've already chosen the best response.43 terms are correct! 5x^2 > one term +x >2nd term 10 > 3rd term but the constant is the term with no ''x" in it, which is ... ?

janice1989

Best ResponseYou've already chosen the best response.0So the answer would be A than correct?

hartnn

Best ResponseYou've already chosen the best response.0the expression 9x^25x7 has __ terms and a constant of ___ 3,7 5,7 3,7 5,7 He said there is 5 terms and a constant of 7 since its right after the x. so he said it would be B correct?

Best ResponseYou've already chosen the best response.0I will for sure tell other parents about it! Ive been stuck on this for such a long time, And someone told me about it, this is an amazing website, Do you also do Geometry?? My daughter is doing geometry and also has special needs she has Aspergers and is having such a hard time with it.. and she is just stressed and all!

hartnn

Best ResponseYou've already chosen the best response.4thank you for the appreciations, yes, i do geometry too :) lets count the terms in , 9x^25x7 9x^2 5x 7 how many ?

janice1989

Best ResponseYou've already chosen the best response.0Than after we finish this up maybe later on you could help my daughter? And he said 3 :)

janice1989

Best ResponseYou've already chosen the best response.0In 6x^43y+5x^410 what are the like terms in the expression choose all that apply.. 6x^4 3y 5x^4 10 he said all of them

Best ResponseYou've already chosen the best response.4like terms are those which have same exponent of 'x' like x^3, 3x^3, 8x^3 .... (one set of like terms) x,4x,9x,x,.... and constants like 4,8,0,1,....

hartnn

Best ResponseYou've already chosen the best response.4in 6x^43y+5x^410 which terms have same exponent of x ?

janice1989

Best ResponseYou've already chosen the best response.0so would it be A & C

hartnn

Best ResponseYou've already chosen the best response.0Yeah he said that, i am just typing for him because he is little bit slow on typing! :D

hartnn

Best ResponseYou've already chosen the best response.0Simplify : 7x^2+2x^2 7x^2 9x^2 14x^4 9x^4 He said he is not sure what to do can you explain it step by step? He said it would either be A or B since the top number are both 2. or do you add them together?

janice1989
 2 years ago
Best ResponseYou've already chosen the best response.0He said would it be B? since 7+2 = 9??

hartnn
 2 years ago
Best ResponseYou've already chosen the best response.4the top number (here 2) is called the exponent. does he know what an exponent is ? and yes, B is correct, because 7x^2+2x^2 = (7+2)x^2 = 9x^2

janice1989

Best ResponseYou've already chosen the best response.0He said hes heard of it, but isnt really sure what it is.

hartnn
 2 years ago
Best ResponseYou've already chosen the best response.4i'll explain, x^n, x is called the 'base' and n is called the exponent. x^n implies , multiplying 'x' to itself, 'n' times. we take an example : 2^4 will imply multiplying 2 4 times = 2*2*2*2 = 16 similarly, x^2 will imply multiplying x with itself twice, x*x got this ?

janice1989

Best ResponseYou've already chosen the best response.0he said oh that is what exponent is i know now! lol. Thank you, hes working on the next one :)

Best ResponseYou've already chosen the best response.0Subtract the second expression from the first (5x^23x+5)(3x^24x7) 2x^2+x+12 2x^27x+12 8x^2+x+12 2x^2+x2 He said would it be B?

hartnn
 2 years ago
Best ResponseYou've already chosen the best response.4why B , how did he get coefficients like 2,7 and 12 ?

janice1989

Best ResponseYou've already chosen the best response.0He says he dont know, i think he was guessing. He does that a lot. Im sorry!

hartnn

Best ResponseYou've already chosen the best response.4(5x^23x+5)(3x^24x7) = 5x^2 3x +5 3x^2  (4x)  (7) {by distributing the negative} = 5x^2 3x +5 3x^2 +4x +7 {because negative times negative becomes positive!} then we identify like terms. but is this much clear ?

janice1989
 2 years ago
Best ResponseYou've already chosen the best response.0he said for like terms would it be 5x^2 3x 3x^2 and 4x?

hartnn
 2 years ago
Best ResponseYou've already chosen the best response.4for like terms , the exponent of x should be same, for which terms exponent of x is 2 ? for which terms exponent of x is 1 ?

hartnn

Best ResponseYou've already chosen the best response.4note x means x^1 , both mean the same

janice1989

Best ResponseYou've already chosen the best response.0he said he is confused. he said he dont get that,

hartnn

Best ResponseYou've already chosen the best response.4ok, the 5x^2 and 3x^2 has exponent of 2 so these are like terms and we can combine them in this way, 5x^23x^2 = (53)x^2 = 2x^2 got this?

hartnn
 2 years ago
Best ResponseYou've already chosen the best response.4cool, from this : 5x^2 3x +5 3x^2 +4x +7 the other like terms are 3x and +4x (because they both contains just x with it, not x^2 or x^3 .....) so we can combine them like : 3x+4x = (3+4) x = ... ?

janice1989
 2 years ago
Best ResponseYou've already chosen the best response.0he said uh he thinks you can combine them not 100% sure

hartnn
 2 years ago
Best ResponseYou've already chosen the best response.4yes, they can be combined because they both have same exponent (=1 here) so, 3x+4x = (3+4) x = x lastly, what remains are just constants, 7+5 , which =12

janice1989

Best ResponseYou've already chosen the best response.0he understands whats next step?

hartnn

Best ResponseYou've already chosen the best response.0distribute and simplify 7(2x4)+2(3x+1) 20x+26 20x26 14x28 6x+2 He asked what is it to distribute???

hartnn

Best ResponseYou've already chosen the best response.4Distribution Property : a(b+c) = ab+ac dw:1379629904908:dw ask if you need an explanation in words....

janice1989

Best ResponseYou've already chosen the best response.0ok he said he got it so far

hartnn

Best ResponseYou've already chosen the best response.4dw:1379630067115:dw so can he fill that now ?

hartnn
 2 years ago
Best ResponseYou've already chosen the best response.4the operation is actually of multiplication while distributing, a(b+c) = a*b + a*c so, that will be = 7*(2x) + 7*(4) got this ? and simplify this further

janice1989
 2 years ago
Best ResponseYou've already chosen the best response.014 &28correct he said?

hartnn
 2 years ago
Best ResponseYou've already chosen the best response.4yeah, just don't forget the 'x' too 7*2x = 14x 7*(4)=28 so, the first part 7(2x4) = 14x28 in same way, please try the second part, 2(3x+1)

hartnn
 2 years ago
Best ResponseYou've already chosen the best response.4good! and whats 2*3x = ... ?

hartnn
 2 years ago
Best ResponseYou've already chosen the best response.42*3x = 6x (again, don't forget the 'x') so we have 7(2x4) +2(3x+1) = 14x28+6x+2 we have distributed successfully, now time to combine like terms, tell him to try first.

janice1989

Best ResponseYou've already chosen the best response.02x, 3x?? and 14x and 6x?

hartnn
 2 years ago
Best ResponseYou've already chosen the best response.4from this 14x28+6x+2 there are only 2 terms containing 'x' , right ? so what is 14x+6x =....?

hartnn

Best ResponseYou've already chosen the best response.4the constants, 28+2 =... ? and so the final answer will be ?

hartnn
 2 years ago
Best ResponseYou've already chosen the best response.4lets check, 3(1.5) + 4(2.5) = 4.5+10 = 14.5 is the numerator. and 14.5/2 = 7.25 is the correct answer! :) :)
