expand (4w-1)^3

Solution

expand

(4 w - 1)^{3}

Solution

64 w^{3} - 48 w^{2} + 12 w - 1

Solution steps

(4 w - 1)^{3}

Apply Perfect Cube Formula:

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

(4 w - 1)^{3} = (4 w)^{3} - 3 (4 w)^{2} \cdot 1 + 3 \cdot 4 w \cdot 1^{2} - 1^{3}

= (4 w)^{3} - 3 (4 w)^{2} \cdot 1 + 3 \cdot 4 w \cdot 1^{2} - 1^{3}

Simplify

(4 w)^{3} - 3 (4 w)^{2} \cdot 1 + 3 \cdot 4 w \cdot 1^{2} - 1^{3} : 64 w^{3} - 48 w^{2} + 12 w - 1

= 64 w^{3} - 48 w^{2} + 12 w - 1
