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

Question

lalaly · Answer

can u rewrite the equation pweez?

anonymous · Answer

not sure how its simple do u know the answer

lalaly · Answer

is x2 >>  x^2?

anonymous · Answer

yes

anonymous · Answer

actually its x^3

lalaly · Answer

x(x^2+8x+7) /(x+8)(x+7)
= x(x+7)(x+1) / (x+8)(x+7)
= x(x+1)/(x+8)

anonymous · Answer

Oh, I knew it was x^3. Okay, on the other question that's just like this one I posted the answer. I'll post it here too

anonymous · Answer

This is what you do.
 1)   x^3+8x^2+7x/x^2+15x+56

 2) x(^2+8x+7)/(x+7) (x+8)

 3) x(x+1)(x+7)/(x+7)(x+8)

 4) x=0 : x=-7 double root : x=-8

You know that there are going to have to be three factors because of the fact that the biggest exponent value in your equation was x^3 the three indicates that there will be 3 factors.
