Simplify the expression by removing parentheses and combining like terms

-3 (2m-2) - 3 (5m-3)

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

-3 (2m - 2) - 3 (5m - 3)

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
