integral from 1 to 2 of 4x^3-3x^2+2x

\int_{1}^{2} 4 x^{3} - 3 x^{2} + 2 x d x

11

Solution steps

\int_{1}^{2} 4 x^{3} - 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} 4 x^{3} d x - \int_{1}^{2} 3 x^{2} d x + \int_{1}^{2} 2 x d x

\int_{1}^{2} 4 x^{3} d x = 15

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

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

= 15 - 7 + 3

Simplify

= 11
