expand (2+y)^3

Solution

expand

(2 + y)^{3}

Solution

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

Solution steps

(2 + y)^{3}

Apply Perfect Cube Formula:

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

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

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

Simplify

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

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