expand 3(x-2y)^3-7(x-2y)^2

expand

3 (x - 2 y)^{3} - 7 (x - 2 y)^{2}

3 x^{3} - 18 x^{2} y + 36 x y^{2} - 24 y^{3} - 7 x^{2} + 28 x y - 28 y^{2}

Solution steps

3 (x - 2 y)^{3} - 7 (x - 2 y)^{2}

Expand

3 (x - 2 y)^{3} : 3 x^{3} - 18 x^{2} y + 36 x y^{2} - 24 y^{3}

= 3 x^{3} - 18 x^{2} y + 36 x y^{2} - 24 y^{3} - 7 (x - 2 y)^{2}

Expand

- 7 (x - 2 y)^{2} : - 7 x^{2} + 28 x y - 28 y^{2}

= 3 x^{3} - 18 x^{2} y + 36 x y^{2} - 24 y^{3} - 7 x^{2} + 28 x y - 28 y^{2}

\frac{6}{1} - x - \frac{4}{1} + x - \frac{8}{x ^{2}} - 1

(v) a^{3} - b^{2} + a - a^{2} \cdot b^{2}

a^{3} + 3 a + 3 a^{2} + 1

\frac{2}{36} - \frac{x ^{6}}{25}

x^{3} + 3 x^{2} + 2 x - 120
