expand (h-1)^3

Solution

expand

(h - 1)^{3}

Solution

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

Solution steps

(h - 1)^{3}

Apply Perfect Cube Formula:

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

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

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

Simplify

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

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