# How do you factor x(3x - yz) + 2yz(3x - yz)?

Feb 13, 2016

(3x - yz)(x + 2yz )

#### Explanation:

in the expression $x \left(3 x - y z\right) + 2 y z \left(3 x - y z\right)$

there is a 'common factor' of (3x - yz )

removing this leaves x in the 1st term and +2yz in the 2nd.

hence factors are : (3x - yz )(x + 2yz )
