How to solve (x+y)^2 + (x^2 -2xy+y^2)

Answer 1

2
`x^(2)`+2
`y^(2)`

Explanation:

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

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

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

`x^(2)`+2xy+
`y^(2)`+
`x^(2)`-2xy+
`y^(2)` (cancel 2xy)

The answer is - 2
`x^(2)`+2
`y^(2)`
