integral from 1 to 2 of (1+2x)

Solution

\int_{1}^{2} (1 + 2 x) d x

Solution

4

Solution steps

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

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

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

= 1 + 3

Simplify

= 4
