integral from-3 to 2 of 6-x-x^2

Solution

\int_{- 3}^{2} 6 - x - x^{2} d x

Solution

\frac{125}{6}

+1

Decimal Notation

20.83333 \dots

Solution steps

\int_{- 3}^{2} 6 - x - x^{2} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{- 3}^{2} 6 d x - \int_{- 3}^{2} x d x - \int_{- 3}^{2} x^{2} d x

\int_{- 3}^{2} 6 d x = 30

\int_{- 3}^{2} x d x = - \frac{5}{2}

\int_{- 3}^{2} x^{2} d x = \frac{35}{3}

= 30 - (- \frac{5}{2}) - \frac{35}{3}

Simplify

30 - (- \frac{5}{2}) - \frac{35}{3} : \frac{125}{6}

= \frac{125}{6}
