expand (x+8)^3

Solution

expand

(x + 8)^{3}

Solution

x^{3} + 24 x^{2} + 192 x + 512

Solution steps

(x + 8)^{3}

Apply Perfect Cube Formula:

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

(x + 8)^{3} = x^{3} + 3 x^{2} \cdot 8 + 3 x \cdot 8^{2} + 8^{3}

= x^{3} + 3 x^{2} \cdot 8 + 3 x \cdot 8^{2} + 8^{3}

Simplify

x^{3} + 3 x^{2} \cdot 8 + 3 x \cdot 8^{2} + 8^{3} : x^{3} + 24 x^{2} + 192 x + 512

= x^{3} + 24 x^{2} + 192 x + 512
