Question

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

Answer 1

`3a(11p - 5m) -5b(13t-5m)`
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.

`( 33ap - 15am) + (- 65bt + 25mb)`

`3a(11p - 5m) -5b(13t-5m)`

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