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
