integral from-1 to 2 of (4x+2)

Solution

\int_{- 1}^{2} (4 x + 2) d x

Solution

12

Solution steps

\int_{- 1}^{2} 4 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} 4 x d x + \int_{- 1}^{2} 2 d x

\int_{- 1}^{2} 4 x d x = 6

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

= 6 + 6

Simplify

= 12
