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

Solution

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

Solution

12

Solution steps

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

\int_{- 1}^{2} 5 d x = 15

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

= 15 - 3

Simplify

= 12
