expand 6(x+2y)^3+8(x+2y)^2

expand

6 (x + 2 y)^{3} + 8 (x + 2 y)^{2}

6 x^{3} + 36 x^{2} y + 72 x y^{2} + 48 y^{3} + 8 x^{2} + 32 x y + 32 y^{2}

Solution steps

6 (x + 2 y)^{3} + 8 (x + 2 y)^{2}

Expand

6 (x + 2 y)^{3} : 6 x^{3} + 36 x^{2} y + 72 x y^{2} + 48 y^{3}

= 6 x^{3} + 36 x^{2} y + 72 x y^{2} + 48 y^{3} + 8 (x + 2 y)^{2}

Expand

8 (x + 2 y)^{2} : 8 x^{2} + 32 x y + 32 y^{2}

= 6 x^{3} + 36 x^{2} y + 72 x y^{2} + 48 y^{3} + 8 x^{2} + 32 x y + 32 y^{2}

16 a^{4} \cdot x^{3} + 54 a \cdot y^{3}

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

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

160000 x^{4} - 10000

a^{2} b^{2} - 25 y^{2}
