integral from 1 to 6 of |x^2-2x-8|

\int_{1}^{6} x^{2} - 2 x - 8 d x

\frac{98}{3}

Decimal Notation

32.66666 \dots

Solution steps

\int_{1}^{6} x^{2} - 2 x - 8 d x

Eliminate Absolutes

= \int_{1}^{4} - x^{2} + 2 x + 8 d x + \int_{4}^{6} x^{2} - 2 x - 8 d x

\int_{1}^{4} - x^{2} + 2 x + 8 d x = 18

\int_{4}^{6} x^{2} - 2 x - 8 d x = \frac{44}{3}

= 18 + \frac{44}{3}

Simplify

18 + \frac{44}{3} : \frac{98}{3}

= \frac{98}{3}

\int_{1}^{4} 3^{4 x} d x

\int_{0}^{6} 2 q^{2} - q + 100 d q

\int_{0}^{x} \frac{1}{2 + t ^{3}} d t

\int_{- 1}^{2} e^{- 3 x} d x

\int_{1}^{6} \frac{4 ( ln ( x ) ) ^{3}}{x} d x
