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

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

60

Solution steps

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

\int_{1}^{4} 3 x^{2} d x = 63

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

\int_{1}^{4} 4 d x = 12

= 63 - 15 + 12

Simplify

= 60
