expand (X-1)^3

Solution

expand

(X - 1)^{3}

Solution

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

Solution steps

(X - 1)^{3}

Apply Perfect Cube Formula:

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

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

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

Simplify

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

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