PLEASE EXPLAIN THE LAST STEP WITH *Factorise: 25(x + y)2 - 36(x - 2y).

1.	PLEASE EXPLAIN THE LAST STEP WITH Factorise: 25(x + y)2 - 36(x - 2y).answer: We have:25(x + y)2 - 36(x – 2y)² = {5(x + y)}? - {6(x - 2y)}?= {5(x + y) + 6(x – 2y)}{5(x + y) - 6(x - 2y)}* = (11x - 7y)(17y - x). **
Answer» $\blue{\underline {\underline {Answer:}}}$ $\orange{\underline {\underline {Step \: By \: Step \: Explaination \: - }}}$ Solving seperately, The QUESTION should be $25 [ x + y ] ^2 - 36 [ x - 2y ] ^2$ = $[ 5(x + y ) ]^2 - [ 6 ( x - 2y )] ^2$ = $[ 5(x + y ) + 6 ( x - 2y ) ] × [ 5( x + y ) - 6 ( x - 2y ) ]$ = $[ 11x - 7y ] × [ 17y - x ]$ {by EXPANDING WITHIN BRAKETS } HOPE you understood.....☝☝☝ $\red{\underline {\underline {Plz \: Follow \: Me \: And \: Mark \: As \: Brainliest !!! }}}$
