expand (d-1)^3

Solution

expand

(d - 1)^{3}

Solution

d^{3} - 3 d^{2} + 3 d - 1

Solution steps

(d - 1)^{3}

Apply Perfect Cube Formula:

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

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

= d^{3} - 3 d^{2} \cdot 1 + 3 d \cdot 1^{2} - 1^{3}

Simplify

d^{3} - 3 d^{2} \cdot 1 + 3 d \cdot 1^{2} - 1^{3} : d^{3} - 3 d^{2} + 3 d - 1

= d^{3} - 3 d^{2} + 3 d - 1
