simplify-{-3x^3-2x^2-[-x^3-(-2x-3x^2)]}

simplify

- {- 3 x^{3} - 2 x^{2} - [- x^{3} - (- 2 x - 3 x^{2})]}

2 x^{3} + 5 x^{2} + 2 x

Solution steps

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

Simplify

- 3 x^{3} - 2 x^{2} - (- x^{3} - (- 2 x - 3 x^{2})) : - 2 x^{3} - 5 x^{2} - 2 x

= - (- 2 x^{3} - 5 x^{2} - 2 x)

Apply the distributive law:

- (- a - b) = a + b

- (- 2 x^{3} - 5 x^{2} - 2 x) = 2 x^{3} + 5 x^{2} + 2 x

= 2 x^{3} + 5 x^{2} + 2 x

(5 p - 3 a)^{3}

a^{3} + a^{- 3}

12 a^{2} + 18 a

(2 \frac{a}{b} - \frac{b}{2} a)^{2}

\frac{n ( n + 1 )}{2 - 2 ^{n} + 1}
