Question

(x + y)(2x + y) + (x + 2y)(x - y)​

Answer 1

Answer:

$(x + y)(2x+ y)+(x + 2y)(x -y)$

$2 {x}^{2} + xy + 2xy + {y}^{2} + {x}^{2} - xy + 2xy - 2 {y}^{2}$

$= > 3 {x}^{2} + 4xy - {y}^{2}$

Answer 2

Answer:

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

2x^2 + xy +2xy + y^2 + x^2-xy +2xy -2y^2

3x^2 + 3xy - y^2 + xy

3x^2 + 4xy -y^2

This is the answer of the given eqn.
