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}
