Question

How do you simplify and restricted value of `[(2x (15x^3 + x + 2) )/ [x^2 (x + 2)] times [(x - 2) (x + 2)] / [15x^3 - 30x^2)`?

Answer 1

`(2x(15x^3+x+2))/(x^2cancel((x+2)))×((x−2)cancel((x+2)))/(15x^3−30x^2)`

`(2x(15x^3+x+2))/(x^2)×(cancel((x−2)))/(15x^2cancel((x-2)))`

`(2x(15x^3+x+2))/(15x^4)`

Now, we have a problematic third order polinomial. I will stop by here:

`(2(15x^3+x+2))/(15x^3)`
