Question

How do you simplify `(y^2 + 2y - 3) / (y^2 - 3y + 2)` and what are the restrictions?

Answer 1

You can factorise both sides of the fraction:

`=((y-1)(y+3))/((y-1)(y-2))`

Restrictions: `y!=1and y!=2`

Then you can simplify to:

`=(y+3)/(y-2)`
graph{(x+3)/(x-2) [-32.47, 32.52, -16.23, 16.23]}
