expand x^3-12x(x-4)-64

expand

x^{3} - 12 x (x - 4) - 64

x^{3} - 12 x^{2} + 48 x - 64

Solution steps

x^{3} - 12 x (x - 4) - 64

Apply the distributive law:

a (b - c) = ab - a c

- 12 x (x - 4) = - 12 xx - (- 12 x) \cdot 4

= x^{3} - 12 xx - (- 12 x) \cdot 4 - 64

Simplify

- 12 xx - (- 12 x) \cdot 4 : - 12 x^{2} + 48 x

= x^{3} - 12 x^{2} + 48 x - 64

x^{2} + 2 2 x - 6

(6 x + 5 y)^{3} - (6 x - 5 y)^{3}

cos (x) sin^{2} (x) + cos^{3} (x)

x - \frac{5}{2} x + 1 - \frac{1}{2}

x^{4} - a^{4} + 4 x^{3} + 4 x^{2}
