Question

(3x+2y)^2-(3x-3y) ^2

Answer 1

9x^2+12xy+4y^2-9x^2+18xy-9y^2
12xy+18xy-5y^2
-5y^2+30xy

Answer 2

HEY mate your and is here....
we can use the formula:- (a²-b²)
therefore,[(3x+2y)+(3x-3y)]×[(3x+2y)-(3x-3y]
=[3x+2y+3x-3y]×[3x+2y-3x+3y]
=[3x+3x+2y-3y]×[3x-3x+2y+3y]
=[6x-y]×[5y]
=30xy-5y²
I hope it's useful
