Answer 2

ANSWER✔

$\red{\text{NOTE:- THE QUESTION IS INCORRECT.}}$

✯CORRECT QUESTION

$\sf\star \:25x^2y^2z^2-36y^2 \: factorise.$

✯FORMULA IN USE,

$\large{\boxed{\bf{ \star\:\: a^2-b^2= (a+b)(a-b)\:\: \star}}}$

$\large\underline\bold{SOLUTION,}$

$\sf\star\: 25x^2y^2z^2-36y^2 \: factorise.$

$\sf\implies y^2(25x^2z^2-36)$

$\sf\implies y^2 \bigg( ( 5xz)^2- (6)^2 \bigg)$

$\sf\implies y^2 (5xz+6)(5xz-6) \:----- \boxed{ by\:given\:identity.}$

$\large{\boxed{\bf{ \star\:\: y^2 (5xz+6)(5xz-6) \:\: \star}}}$
