integral from 3 to 6 of x^2-3x

Solution

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

Solution

\frac{45}{2}

+1

Decimal Notation

22.5

Solution steps

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

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

\int_{3}^{6} 3 x d x = \frac{81}{2}

= 63 - \frac{81}{2}

Simplify

63 - \frac{81}{2} : \frac{45}{2}

= \frac{45}{2}
