Answer:
3a^2 - 6b + 2ab
Step-by-step explanation:
Add like terms together so shifting the equation a little to make it easier to add:
4a^2 - 7b + 2ab - a^2 + b
4a^2 - a^2 - 7b + b + 2ab
3a^2 - 6b + 2ab
Answer:
3a^2 - 6b + 2ab
Step-by-step explanation:
Put all the like terms together
(4a^2 - a^2) - (7b + b) + 2ab
then simplify
(4a^2 - a^2) = 3a^2
(-7b + b) = -6b
then rewrite
3a^2 - 6b + 2ab
