expand (4-2x)^3

Solution

expand

(4 - 2 x)^{3}

Solution

64 - 96 x + 48 x^{2} - 8 x^{3}

Solution steps

(4 - 2 x)^{3}

Apply Perfect Cube Formula:

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

(4 - 2 x)^{3} = 4^{3} - 3 \cdot 4^{2} \cdot 2 x + 3 \cdot 4 (2 x)^{2} - (2 x)^{3}

= 4^{3} - 3 \cdot 4^{2} \cdot 2 x + 3 \cdot 4 (2 x)^{2} - (2 x)^{3}

Simplify

4^{3} - 3 \cdot 4^{2} \cdot 2 x + 3 \cdot 4 (2 x)^{2} - (2 x)^{3} : 64 - 96 x + 48 x^{2} - 8 x^{3}

= 64 - 96 x + 48 x^{2} - 8 x^{3}
