integral from 2 to 5 of (2x-1)

Solution

\int_{2}^{5} (2 x - 1) d x

Solution

18

Solution steps

\int_{2}^{5} 2 x - 1 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_{2}^{5} 2 x d x - \int_{2}^{5} 1 d x

\int_{2}^{5} 2 x d x = 21

\int_{2}^{5} 1 d x = 3

= 21 - 3

Simplify

= 18
