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

Solution

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

Solution

69

Solution steps

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

\int_{1}^{4} 4 x^{2} d x = 84

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

= 84 - 15

Simplify

= 69
