expand (a+b)^3-16(a+b)

expand

(a + b)^{3} - 16 (a + b)

a^{3} + 3 a^{2} b + 3 a b^{2} + b^{3} - 16 a - 16 b

Solution steps

(a + b)^{3} - 16 (a + b)

Expand

(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} - 16 (a + b)

Expand

- 16 (a + b) : - 16 a - 16 b

= a^{3} + 3 a^{2} b + 3 a b^{2} + b^{3} - 16 a - 16 b

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

\frac{9}{x} - \frac{8}{t}

(3 a + 4 z)^{7}

9 c^{0} (0.8)^{0} (1 - 0.6)^{9}

\frac{( b ^{4} )}{( 2 b )}
