Is Ava's solution correct? If not, find and explain her mistake. Give the correct solution.

Answer 1

$\huge{\mathcal{\blue{\underline{\underline{\pink{HeYa!!!}}}}}}$

${\huge{\purple{\mathbb{\bold{ANSWER}}}}}$

▪︎ Ava's solution is not correct.

${\large{\blue{\bold{\underline{You\: must\: know:-}}}}}$

=》 (a-b)² = (b-a)²

▪︎ Because:-

=》(a-b)²

= a²-2ab+b²

= a²+b²-2ab.

▪︎ And,

=》 (b-a)²

= b²-2ab+a².

= a²+b²-2ab.

${\large{\blue{\bold{\underline{Therefore,}}}}}$

=》 (a-b)² = (a+b)²

${\large{\blue{\bold{\underline{Correct\:Process:-}}}}}$

=》 (2x-3y)²/(3y-2x)².

= (2x-3y)²/(2x-3y)².

${\large{\red{\boxed{\bold{=\:1.}}}}}$

Hope this will help you if it HELPS then plz mark my answer as BRAINLIEST.
