integral from 1 to 2 of 3x+2

Solution

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

Solution

\frac{13}{2}

+1

Decimal Notation

6.5

Solution steps

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

\int_{1}^{2} 3 x d x = \frac{9}{2}

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

= \frac{9}{2} + 2

Simplify

\frac{9}{2} + 2 : \frac{13}{2}

= \frac{13}{2}
