expand (d-2)^3

Solution

expand

(d - 2)^{3}

Solution

d^{3} - 6 d^{2} + 12 d - 8

Solution steps

(d - 2)^{3}

Apply Perfect Cube Formula:

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

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

= d^{3} - 3 d^{2} \cdot 2 + 3 d \cdot 2^{2} - 2^{3}

Simplify

d^{3} - 3 d^{2} \cdot 2 + 3 d \cdot 2^{2} - 2^{3} : d^{3} - 6 d^{2} + 12 d - 8

= d^{3} - 6 d^{2} + 12 d - 8
