Step 1 ) Distribute the parenthesis.
-3 ( 2m - 2 ) -3 ( 5m - 3 )
−6m + 6 − 15m + 9
Step 2 ) Combine like terms.
−6m + 6 − 15m + 9
-6m - 15m + 6 + 9
-21m + 15
The expression is in its simplest form, so the answer is...
-21m + 15

The first step is to get rid of the parentheses by applying this Distributive Property. The Distributive Property: a(b + c) = ab + ac.
Mutiply each term inside the parentheses by the multiplier outside of it.
-3(2m - 2) - 3(5m - 3)
-6m + 6 - 3(5m - 3)
-6m + 6 - 15m + 9
Collect like terms (variable terms and constants).
-6m + 6 - 15m + 9
-21m + 15
Answer:
-21m + 15
