integral from-1 to 2 of x+2

Solution

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

Solution

\frac{15}{2}

+1

Decimal Notation

7.5

Solution steps

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

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

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

= \frac{3}{2} + 6

Simplify

\frac{3}{2} + 6 : \frac{15}{2}

= \frac{15}{2}
