expand (x+a)^3

Solution

expand

(x + a)^{3}

Solution

x^{3} + 3 a x^{2} + 3 x a^{2} + a^{3}

Solution steps

(x + a)^{3}

Apply Perfect Cube Formula:

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

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

= x^{3} + 3 x^{2} a + 3 x a^{2} + a^{3}

= x^{3} + 3 a x^{2} + 3 x a^{2} + a^{3}
