expand (d-5)^3

Solution

expand

(d - 5)^{3}

Solution

d^{3} - 15 d^{2} + 75 d - 125

Solution steps

(d - 5)^{3}

Apply Perfect Cube Formula:

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

(d - 5)^{3} = d^{3} - 3 d^{2} \cdot 5 + 3 d \cdot 5^{2} - 5^{3}

= d^{3} - 3 d^{2} \cdot 5 + 3 d \cdot 5^{2} - 5^{3}

Simplify

d^{3} - 3 d^{2} \cdot 5 + 3 d \cdot 5^{2} - 5^{3} : d^{3} - 15 d^{2} + 75 d - 125

= d^{3} - 15 d^{2} + 75 d - 125
