expand (x-y)^3-1

expand

(x - y)^{3} - 1

x^{3} - 3 x^{2} y + 3 x y^{2} - y^{3} - 1

Solution steps

(x - y)^{3} - 1

Apply Perfect Cube Formula:

(a - b)^{3} = a^{3} - 3 a^{2} b + 3 a b^{2} - b^{3}

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

= x^{3} - 3 x^{2} y + 3 x y^{2} - y^{3} - 1

(x - 2 y + 2) 2

28 n^{1} + 16 n^{3} - 80 n^{2}

(\frac{p ^{4}}{c ^{6}})^{9}

(2 p - 3 p)^{3}

\frac{d ^{5}}{d ^{x}}
