First, distribute the terms inside the parentheses:
M(-6m - 4) = -6M^2 - 4M9m(-3m + 6) = -27m^2 + 54m
Now, add the two expressions together:
-6M^2 - 4M + (-27m^2 + 54m)= -6M^2 - 27M^2 - 4M + 54m= -33M^2 + 50m
So, M (-6m - 4) + 9m (-3m + 6) simplifies to -33M^2 + 50m.
First, distribute the terms inside the parentheses:
M(-6m - 4) = -6M^2 - 4M
9m(-3m + 6) = -27m^2 + 54m
Now, add the two expressions together:
-6M^2 - 4M + (-27m^2 + 54m)
= -6M^2 - 27M^2 - 4M + 54m
= -33M^2 + 50m
So, M (-6m - 4) + 9m (-3m + 6) simplifies to -33M^2 + 50m.
