Question

Factorize:
x^2+x-y-y^2

Answer 1

Answer:

x^2+x-y-y^2

x(x+1) -y ( 1+y)

(x-y) ( 1+x) ( 1+y)

x=y , x = -1 , y= -1

Answer 2

Step-by-step explanation:

Re combining the terms

$({x}^{2} - {y}^{2}) + (x - y)$

applying identity a²-b²=(a+b)(a-b)

$(x + y)(x - y) + (x - y)$

taking (x-y) as common

$(x - y)(x + y + 1)$
