How do you find the reverse distributive property of # 3p - 6q + 12r#?
Divide out the highest common factor from the terms.
This process would be the same as 'factorise'.
What factor do all of the terms contain?
That number would have been in front of a bracket and have been multiplied by all the terms in the bracket.
If you now apply the distributive property you will end up with the expression you started with.
