expand (y+2)^3

Solution

expand

(y + 2)^{3}

Solution

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

Solution steps

(y + 2)^{3}

Apply Perfect Cube Formula:

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

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

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

Simplify

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

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