Question

What is the simplified form of `(y^2+y-20)/(y^2-y-12)`?

Answer 1

`(y+5)/(y+3)`

Explanation:

`(y^2+y-20)/(y^2-y-12)=((y+5)(y-4))/((y-4)(y+3))`

The factor of (y-4) cancels out as `(y-4)/(y-4)=1`

This leaves us with the solution of;

`(y^2+y-20)/(y^2-y-12)=(y+5)/(y+3)`

Hope it helps :)
