# How do you factor 3h ^ { 2} - 30h - 33?

May 16, 2017

Answer: $3 \left(h - 11\right) \left(h + 1\right)$

#### Explanation:

Factor $3 {h}^{2} - 30 h - 33$

First we can see that each term has a common factor of $3$ which we can factor out:
$= 3 \left({h}^{2} - 10 h - 11\right)$

Now, we can more easily factor (two numbers multiplied together is -11 and added together is -10):
$= 3 \left(h - 11\right) \left(h + 1\right)$
