expand (4b+6y)^3

expand

(4 b + 6 y)^{3}

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

Solution steps

(4 b + 6 y)^{3}

Apply Perfect Cube Formula:

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

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

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

Simplify

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

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

4 \cdot (\frac{1}{y + 1})^{6}

(\frac{2 y - 1}{3 y})^{3}

2.5 \cdot 10 - 7 m

6 m^{5} + 1 + 2 m^{5} + 9 m - 1

\frac{( 5 x - 15 ) \cdot x ^{3} x}{2}
