integral from 3 to 6 of x^2+3

Solution

\int_{3}^{6} x^{2} + 3 d x

Solution

72

Solution steps

\int_{3}^{6} x^{2} + 3 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_{3}^{6} x^{2} d x + \int_{3}^{6} 3 d x

\int_{3}^{6} x^{2} d x = 63

\int_{3}^{6} 3 d x = 9

= 63 + 9

Simplify

= 72
