expand (-x-y)^2

Solution

expand

(- x - y)^{2}

Solution

x^{2} + 2 x y + y^{2}

Solution steps

(- x - y)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

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

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

Simplify

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

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