expand (6-4y)^3

Solution

expand

(6 - 4 y)^{3}

Solution

216 - 432 y + 288 y^{2} - 64 y^{3}

Solution steps

(6 - 4 y)^{3}

Apply Perfect Cube Formula:

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

(6 - 4 y)^{3} = 6^{3} - 3 \cdot 6^{2} \cdot 4 y + 3 \cdot 6 (4 y)^{2} - (4 y)^{3}

= 6^{3} - 3 \cdot 6^{2} \cdot 4 y + 3 \cdot 6 (4 y)^{2} - (4 y)^{3}

Simplify

6^{3} - 3 \cdot 6^{2} \cdot 4 y + 3 \cdot 6 (4 y)^{2} - (4 y)^{3} : 216 - 432 y + 288 y^{2} - 64 y^{3}

= 216 - 432 y + 288 y^{2} - 64 y^{3}
