expand (8x-2)^3

Solution

expand

(8 x - 2)^{3}

Solution

512 x^{3} - 384 x^{2} + 96 x - 8

Solution steps

(8 x - 2)^{3}

Apply Perfect Cube Formula:

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

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

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

Simplify

(8 x)^{3} - 3 (8 x)^{2} \cdot 2 + 3 \cdot 8 x \cdot 2^{2} - 2^{3} : 512 x^{3} - 384 x^{2} + 96 x - 8

= 512 x^{3} - 384 x^{2} + 96 x - 8
