integral from 0 to 3 of 5x-x^2

Solution

\int_{0}^{3} 5 x - x^{2} d x

Solution

\frac{27}{2}

+1

Decimal

13.5

Solution steps

\int_{0}^{3} 5 x - 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_{0}^{3} 5 x d x - \int_{0}^{3} x^{2} d x

\int_{0}^{3} 5 x d x = \frac{45}{2}

\int_{0}^{3} x^{2} d x = 9

= \frac{45}{2} - 9

Simplify

\frac{45}{2} - 9 : \frac{27}{2}

= \frac{27}{2}
