expand a((a-b)*(a+2b))

Solution

expand

a ((a - b) \cdot (a + 2 b))

Solution

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

Solution steps

a ((a - b) (a + 2 b))

Remove parentheses:

(a) = a

= a (a - b) (a + 2 b)

Expand

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

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

Expand

a (a^{2} + ab - 2 b^{2}) : a^{3} + a^{2} b - 2 a b^{2}

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