# How do you factor the expression 5ax^2-2bx^2-15ay+6by as the product of two binomials?

Jan 7, 2017

The answer is $= \left({x}^{2} - 3 y\right) \left(5 a - 2 b\right)$

#### Explanation:

We factorise 2 terms by 2 terms

$5 a {x}^{2} - 2 b {x}^{2} - 15 a y + 6 b y$

$= {x}^{2} \left(5 a - 2 b\right) - 3 y \left(5 a - 2 b\right)$

$= \left({x}^{2} - 3 y\right) \left(5 a - 2 b\right)$
