Answer:
14x^2y^2 - 21x^2y + 56xy^2 + 63xy
Step-by-step explanation:
Remark
This is a disguised form of the distributive property. Nothing can be simplified inside the brackets. So the plan is to remove them.
7xy*2xy - 3x*7xy + 8y*7xy + 9*7xy Combine the terms
14x^2y^2 - 21x^2y + 56xy^2 + 63xy
You cannot symplify anything further. If nothing could be combined before, it cannot be simplified now.
