simplify 3(x+y)-(x+y)^2

Solution

simplify

3 (x + y) - (x + y)^{2}

Solution

3 x + 3 y - x^{2} - 2 x y - y^{2}

Solution steps

3 (x + y) - (x + y)^{2}

(x + y)^{2} : x^{2} + 2 x y + y^{2}

= 3 (x + y) - (x^{2} + 2 x y + y^{2})

Expand

3 (x + y) : 3 x + 3 y

= 3 x + 3 y - (x^{2} + 2 x y + y^{2})

- (x^{2} + 2 x y + y^{2}) : - x^{2} - 2 x y - y^{2}

= 3 x + 3 y - x^{2} - 2 x y - y^{2}
