Answer:
2a²-2b²-ab
Step-by-step explanation:
(3a-b²+2ab) - (a²+b²+ab)
we should open brackets and we know that if we open bracket after minus sign, inside signs were changed.
like - in - is +
- in + or + in - is -
+ in + is +
so,
3a²-b²+2ab-a²-b²-ab
+3a²-a²=2a²
-b²-b²=-2b²
+2ab-ab=ab
so,
Answer:- 2a²-2b²-ab
