integral from-7 to 4 of-x^2-3x

Solution

\int_{- 7}^{4} - x^{2} - 3 x d x

Solution

- \frac{517}{6}

+1

Decimal

- 86.16666 \dots

Solution steps

\int_{- 7}^{4} - x^{2} - 3 x 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_{- 7}^{4} x^{2} d x - \int_{- 7}^{4} 3 x d x

\int_{- 7}^{4} x^{2} d x = \frac{407}{3}

\int_{- 7}^{4} 3 x d x = - \frac{99}{2}

= - \frac{407}{3} - (- \frac{99}{2})

Simplify

- \frac{407}{3} - (- \frac{99}{2}) : - \frac{517}{6}

= - \frac{517}{6}
