Question

x2+8x^2+7x over x^2+15x+56. simplify

Answer 1

are you quite sure it's x^2 and not x^3

Answer 2

Well then, I'll solve what you have then.

Answer 3

You need to work out the bottom first.

Like so: x^2+8x^2+7x/(x+7)(x+8)

Answer 4

If the way you posted the top is correct, then it will be like this:

Combine the like terms: x^2+8x^2= 9x^2
which is now:
9x^2+7x/(x+7)(x+8)

Answer 5

From here all you can possibly do is factor out the x on the top function and you have your x's:

x(9x+7)/(x+7)(x+8)
