Question

factorise the x^2 + 2xy + y^2 + zx + zy using the identity (a+b)^2=a^2+2ab+b^2




please explain step by step​

Answer 1

SOLUTION:–

x²+2xy + y² +zx + zy

se first 3 term , it is an identity of (x+y)²

& take "z" as common from 4th &5th term

(x+y)²+ z(x+y) [ now take (x+y) as common ]

(x+y)(x+y+z) ANS

HOPE IT HELPS YOU.
