Answer:
Step-by-step explanation:
4x^2y^2+3xy+3xy^2
= xy(4xy+3+3y)
8xy^2-4x^2y+7x^2y^2+10xy
=xy(8y-4x+7xy+10)
xy(4xy+3+3y)-xy(8y-4x+7xy+10)
=xy(4xy+3+3y-(8y-4x+7xy+10))
=xy(4xy+3+3y-8y+4x-7xy-10)
=xy(-3xy-7-5y+4)
∴ xy(-3xy-7-5y+4) must be removed
(P.s. make sure to check my answer again my urself!!!)
