## Homework Equations

## The Attempt at a Solution

so at the bottom of the page, it ends up converting

(1/6)(√x-10)

^{3}(3√x+10)

to

(x/6)(3x-80√x+600)

The problem is, when I try the simplification by myself, i always end up with 3x^2-80x^1.5+600x-10000. I realize I can simplify by x giving me

x(3x-80x^.5+600-10000/x)

Why does the answer given not have this extra 10000/x at the end?

Thanks
