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

expand

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

8 x^{3} - 12 x^{2} y + 6 x y^{2} - y^{3} + x^{2} - y^{2}

Solution steps

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

Expand

(2 x - y)^{3} : 8 x^{3} - 12 x^{2} y + 6 x y^{2} - y^{3}

= 8 x^{3} - 12 x^{2} y + 6 x y^{2} - y^{3} + (x + y) (x - y)

Expand

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

= 8 x^{3} - 12 x^{2} y + 6 x y^{2} - y^{3} + x^{2} - y^{2}
