# How do you factor  33ap - 15am - 65bt + 25mb?

Jul 16, 2016

$3 a \left(11 p - 5 m\right) - 5 b \left(13 t - 5 m\right)$
It does not seem to factor further?

#### Explanation:

There are 4 terms and there is no common factor. Group the terms in pairs to have a common factor in each- make sure there is a + sign between the pairs.

$\left(33 a p - 15 a m\right) + \left(- 65 b t + 25 m b\right)$

$3 a \left(11 p - 5 m\right) - 5 b \left(13 t - 5 m\right)$

This does not factor further as there is no common bracket.
