# How do you simplify (m^2 - 5m - 14)/(m^2 - 4m + 4) and what are the restrictions?

Jul 13, 2015

First you factorise:

#### Explanation:

$= \frac{\left(m + 2\right) \left(m - 7\right)}{\left(m - 2\right) \left(m - 2\right)}$

As you see, there's nothing to simplify.

Restriction is that the numerator may not be $= 0$, so:

$m \ne 2$
