expand (a+b)^3-a-b

expand

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

a^{3} + 3 a^{2} b + 3 a b^{2} + b^{3} - a - b

Solution steps

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

Apply Perfect Cube Formula:

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

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

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

(1 + \frac{x}{2} - \frac{2}{x})^{4}

\frac{4}{( x )}

12 c - 28 d + 52

(\frac{0.5 - 2 x}{0.5})^{2}

\frac{- 6}{5 x ^{2}}
