Answer: -2m2 -m - 10
Step-by-step explanation:
(-5m2 - 8) - (-3m2 + m + 2)
Everything is behind the (-) when you have a parenthesis chang the sign so and let the () so will be
-5m2-8 +3m2 - m -2
Now you are going to add or subtract numbers for the one the same letter ( base) and for the one that don't have a other letter (base) you will let it like this so will be
-5m2 + 3m2 = -2m2
-8 -2 = -10
-2m2 - m - 10
Hope helps
