expand (s+1)^3

Solution

expand

(s + 1)^{3}

Solution

s^{3} + 3 s^{2} + 3 s + 1

Solution steps

(s + 1)^{3}

Apply Perfect Cube Formula:

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

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

= s^{3} + 3 s^{2} \cdot 1 + 3 s \cdot 1^{2} + 1^{3}

Simplify

s^{3} + 3 s^{2} \cdot 1 + 3 s \cdot 1^{2} + 1^{3} : s^{3} + 3 s^{2} + 3 s + 1

= s^{3} + 3 s^{2} + 3 s + 1
