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

Jun 4, 2015

You can factorise both sides of the fraction:

$= \frac{\left(y - 1\right) \left(y + 3\right)}{\left(y - 1\right) \left(y - 2\right)}$

Restrictions: $y \ne 1 \mathmr{and} y \ne 2$

Then you can simplify to:

$= \frac{y + 3}{y - 2}$
