integral from 1 to 2 of (20x^3+6/(x^2))

\int_{1}^{2} (20 x^{3} + \frac{6}{x ^{2}}) d x

78

Solution steps

\int_{1}^{2} 20 x^{3} + \frac{6}{x ^{2}} 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} 20 x^{3} d x + \int_{1}^{2} \frac{6}{x ^{2}} d x

\int_{1}^{2} 20 x^{3} d x = 75

\int_{1}^{2} \frac{6}{x ^{2}} d x = 3

= 75 + 3

Simplify

= 78
