# How do you factor 18y^2 - 6 ?

Apr 20, 2018

$\implies 6 \left(3 {y}^{2} - 1\right)$

#### Explanation:

$\implies 18 {y}^{2} - 6$

The greatest common factor of $18$ and $6$ is $6$, so we can factor that out.

$\implies 6 \left(3 {y}^{2} - 1\right)$

This cannot be simplified further. So the final factored form is:

$\implies 6 \left(3 {y}^{2} - 1\right)$
