I 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??

like 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,....

in 6x^43y+5x^410 which terms have same exponent of x ?

Simplify : 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?
 one year ago

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

hartnn Group TitleBest ResponseYou've already chosen the best response.4
the 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
 one year ago

janice1989 Group TitleBest ResponseYou've already chosen the best response.0
He said hes heard of it, but isnt really sure what it is.
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.4
i'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 ?

Subtract 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?
 one year ago

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

janice1989 Group TitleBest ResponseYou've already chosen the best response.0
He says he dont know, i think he was guessing. He does that a lot. Im sorry!
 one year ago

hartnn Group TitleBest 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 ?
 one year ago

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

hartnn Group TitleBest ResponseYou've already chosen the best response.4
for 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 ?
 one year ago

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

janice1989 Group TitleBest ResponseYou've already chosen the best response.0
he said he is confused. he said he dont get that,
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.4
ok, 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?
 one year ago

janice1989 Group TitleBest ResponseYou've already chosen the best response.0
got it he said
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.4
cool, 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 = ... ?
 one year ago

janice1989 Group TitleBest ResponseYou've already chosen the best response.0
he said uh he thinks you can combine them not 100% sure
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.4
yes, 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

7 2x + 72
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.4
the 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
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.4
like 7*(4) = 28,

14 &28correct he said?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.4
yeah, 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 Group TitleBest ResponseYou've already chosen the best response.4
2*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.

2x, 3x?? and 14x and 6x?

from this 14x28+6x+2 there are only 2 terms containing 'x' , right ? so what is 14x+6x =....?

evaluate the expression 2(x+y)  for x=6 and y=7 3 13/3 19/3 20/3 26/3 he said its look like this 2(6+7)  3 he said would the answer be 26/3??

Evaluate the expression 3x+4y  x=1.5 and y=2.5 2 2 4.25 6.25 7.25 His work 3(1.5) +4(2.5)  2 would it be 7.25?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.4
lets 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! :) :)
