Question

4. गुणनखंड ज्ञात कीजिए-
(a) (x +y) + 2(x + y)(x-y) + (x-y)​

Answer 1

Answer:

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

=x+y+2x^2-2y^2+x-y

=2x^2-2y^2+2x

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

Answer 2

Answer:

$(x + y) + 2(x + y)(x - y) + (x - y) \\ x + y + 2( {x}^{2} - xy + xy - {y}^{2}) + x - y \\ x + y + 2 {x}^{2} - 2 {y}^{2} + x - y \\ 2 {x}^{2} - 2 {y}^{2} + 2x \\ thank \: you$
