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

Solution

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

Solution

\frac{111}{4}

+1

Decimal Notation

27.75

Solution steps

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

\int_{- 1}^{2} x^{3} d x = \frac{15}{4}

\int_{- 1}^{2} 8 d x = 24

= \frac{15}{4} + 24

Simplify

\frac{15}{4} + 24 : \frac{111}{4}

= \frac{111}{4}
