integral from 1 to 2 of 3x^2-2x

Solution

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

Solution

4

Solution steps

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

\int_{1}^{2} 3 x^{2} d x = 7

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

= 7 - 3

Simplify

= 4
