expand (h+2)^3

Solution

expand

(h + 2)^{3}

Solution

h^{3} + 6 h^{2} + 12 h + 8

Solution steps

(h + 2)^{3}

Apply Perfect Cube Formula:

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

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

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

Simplify

h^{3} + 3 h^{2} \cdot 2 + 3 h \cdot 2^{2} + 2^{3} : h^{3} + 6 h^{2} + 12 h + 8

= h^{3} + 6 h^{2} + 12 h + 8
