Question

(x+y) ka whole square - (x-y) ka whole square? you solved this question step by step

Answer 1

(x+y)^2-(x-y)^2
(x^2+y^2+2xy)-(x^2+y^2-2xy)
=2xy+2xy
=4xy

Answer 2

Heya,

(x+y)^2-(x-y)^2

=> (x^2+2xy+y^2)-(x^2-2xy+y^2) [Factorization by Algebraic identifies]

=> x^2+2xy+y^2-x^2+2xy-y^2 [Change the symbol]

=> +2xy+2xy [Add]

=> +4xy

Hope my answer helps you :)
