integral from 0 to 9 of x^2-4

Solution

\int_{0}^{9} x^{2} - 4 d x

Solution

207

Solution steps

\int_{0}^{9} x^{2} - 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_{0}^{9} x^{2} d x - \int_{0}^{9} 4 d x

\int_{0}^{9} x^{2} d x = 243

\int_{0}^{9} 4 d x = 36

= 243 - 36

Simplify

= 207
