expand (b-a)^3

Solution

expand

(b - a)^{3}

Solution

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

Solution steps

(b - a)^{3}

Apply Perfect Cube Formula:

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

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

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