integral from-1 to 3 of 2x^2+8

Solution

\int_{- 1}^{3} 2 x^{2} + 8 d x

Solution

\frac{152}{3}

+1

Decimal

50.66666 \dots

Solution steps

\int_{- 1}^{3} 2 x^{2} + 8 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_{- 1}^{3} 2 x^{2} d x + \int_{- 1}^{3} 8 d x

\int_{- 1}^{3} 2 x^{2} d x = \frac{56}{3}

\int_{- 1}^{3} 8 d x = 32

= \frac{56}{3} + 32

Simplify

\frac{56}{3} + 32 : \frac{152}{3}

= \frac{152}{3}
