Homework Help: math

Posted by bob on Wednesday, February 14, 2007 at 5:11pm.

how do i do x2+12x+32

x2+12x = 14x+32

subtract 14x from each side

14x=32

divide by 2

7x=16

x=16/7, which is 2 and 2/7

ok maybe you typed that question wrong?

is it x^2 + 12x + 32 ?

if it is then the solution is:

(x+8)(x+4)

because when you multiply them you use foil; so multiply x with the other x to get x^2, then multiply the x with the 4 to get 4x. Next you take 8 and multiply it with the x to get 8x, then multiply 8 with 4 to get 32.

you should've gotten this:
x^2 + 4x + 8x + 32

then simplify(add the 4x + 8x) which in turn equals x^2+12x+32.

I agree with Donna. But the question is what is the problem
