expand (-(-2)(2(-2)^2+3(-2)-12))/3

expand

\frac{- ( - 2 ) ( 2 ( - 2 ) ^{2} + 3 ( - 2 ) - 12 )}{3}

- \frac{20}{3}

Decimal Notation

- 6.66666 \dots

Solution steps

\frac{- ( - 2 ) ( 2 ( - 2 ) ^{2} + 3 ( - 2 ) - 12 )}{3}

Remove parentheses:

(- a) = - a, - (- a) = a

= \frac{2 ( 2 ( - 2 ) ^{2} - 3 \cdot 2 - 12 )}{3}

2 (2 (- 2)^{2} - 3 \cdot 2 - 12) = - 20

= \frac{- 20}{3}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{20}{3}

\frac{2 ( 2 x - T )}{T}

\frac{1}{r ( n - r )}

\frac{d}{d t} ((r (t)) (2 sin (t) - e^{- t}))

(\frac{x}{3} + \frac{y}{6} + z = 1) 6

\frac{9 + 27 s + 3 s ^{3}}{( 9 + s ^{2} ) ^{2}}
