expand (r-h)^3

Solution

expand

(r - h)^{3}

Solution

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

Solution steps

(r - h)^{3}

Apply Perfect Cube Formula:

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

(r - h)^{3} = r^{3} - 3 r^{2} h + 3 r h^{2} - h^{3}

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

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