.:-Factorize:- (a)X - (y+2) (b) 1+ 2xy-(x +y) I will mark you brainiest and free points if you tell me this answer plz fast​

Answer»

The FACTOR of 1−X 2 −2xy−y 2 isRearranging the terms⇒ 1−(x 2 +2xy+y 2 )⇒ −1(x+y) 2 [∵ (x+y) 2 =x 2 +2xy+y 2 ]⇒ (1−(x+y) 2 )⇒ (1) 2 =(x+y) 2 [∵(1)2 =1]USING a 2 −b 2 =(a+b)(a−b)⇒ (1−(x+y))(1+(x+y))⇒ (1−x−y)(1+x+y)
