Best ResponseYou've already chosen the best response.0You take half of the x term so half of 8 = 4 Then you square that answer 4^2 = 16

Best ResponseYou've already chosen the best response.0do you know what the formula for (a+b)^2 is?

anonymous

Best ResponseYou've already chosen the best response.0in other words, \[(a+b)^{2} = ?\]

Best ResponseYou've already chosen the best response.0okay, \[(a+b)^{2} = a ^{2}+ 2ab +b ^{2}\]

Best ResponseYou've already chosen the best response.0so the example that i just put up how would that work

Best ResponseYou've already chosen the best response.0compare \[x ^{2}+8x  11.\] and \[a ^{2}+2ab+b ^{2}\]

Best ResponseYou've already chosen the best response.0so what must you add to 11 to make it into b^2?

anonymous

Best ResponseYou've already chosen the best response.0okay try again. when you compare the two equations, you see that x = a. correct? and 2ab = 8x. so find the value of b.

Best ResponseYou've already chosen the best response.0idk , im srry im not Tht qood in math

anonymous

Best ResponseYou've already chosen the best response.0okay, 2ab = 8x, divide by 2a on both sides. => b = 8x/2a you know that x = a so what is the value of b?

Best ResponseYou've already chosen the best response.0so for (a+b)^2 to be equal to (x+4)^2, what must you add to x^2 +8x11?

anonymous

Best ResponseYou've already chosen the best response.0maybe 2 0r 4 because i did 8\[\div\]2 qive me 4 then i square root that and qave me 2.

anonymous

Best ResponseYou've already chosen the best response.0what? you found out that x = a and 4 = b. so your complete square is (x+4)^2. so expand (x+4)^2 using the formula i gave earlier.

anonymous

Best ResponseYou've already chosen the best response.0okay \[(x+4)^{2}= x ^{2}+8x+16\]

anonymous

Best ResponseYou've already chosen the best response.0you are in 12th grade and don't know what (a+b)^2 is ?That is very surprising. Anyway, compare the expanded version of (x+4)^2 i gave you with your original formula, x2+8x11

anonymous

Best ResponseYou've already chosen the best response.0how much do you need to add to x2+8x11 to get x2+8x+16?

anonymous

Best ResponseYou've already chosen the best response.0itss not because to mee math is hard for one and for two yu dont have to help mee someone else can if its like that im on here for help not for someone to tell im in the 12th i dont know what something is i guess maybe it dont get through to mee to many smart retricepeople wrong thing for me to come to flutter .

Best ResponseYou've already chosen the best response.0make some sense. I did not want to offend you. I was just surprised. I thought basic algebra was taught in 8th grade or something.

anonymous

Best ResponseYou've already chosen the best response.0you know what flutter you and your negative attititude if yu aint going to help go some where with you ignorgant self and it probably was and wht its 2011 not 2007
