you're gonna have 2y^2 - 2y^2 which cancel out giving you 0 so they dont go into the simplified answer. then, since 30xy is the only one that doesnt have a match you place that down. then place +4y , and then -4x . It will give you 30xy +4y -4x .
or vise versa with the 4y and 4x . whichever your answer choices are or how u prefer to write it. <3
