Question

xsquare-2xy+ysquare)-zsquare

Answer 1

(x-y+z)(x-y-z) this was answers

Answer 2

( x² - 2xy + y² ) - z²



$\mathbf{we \: know \: \: \: {a}^{2} - 2ab + {b}^{2} = {(a - b)}^{2} }$


Hence,


=> ( x - y )² - z²


$\mathbf{formula \: \: \: \: \: \: \: \: \: \: \: \: {a}^{2} - {b}^{2} = (a + b)(a - b)}$


Applying formula,


=> ( x - y + z ) ( x - y - z )
