Answer 2

Answer:

$\sf \: x(x²- y²) - y(x² - y²)$

$\sf \: Taking \: \: x {}^{2} - y {}^{2} \: common \: here$

$\sf \: (x {}^{2} - y {}^{2} )(x - y)$

$\sf \: \: (x + y) \: (x - y) \:(x - y)$

$\sf \: As \: We \: Know \: That \: (x {}^{2} - y {}^{2} )$

$\sf \: Hence, \: Answer \: is \: \pink{(x + y) \: (x - y)^2}$
