integral from 0 to 3 of x^2-5x+6

Solution

\int_{0}^{3} x^{2} - 5 x + 6 d x

Solution

\frac{9}{2}

+1

Decimal

4.5

Solution steps

\int_{0}^{3} x^{2} - 5 x + 6 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} x^{2} d x - \int_{0}^{3} 5 x d x + \int_{0}^{3} 6 d x

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

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

\int_{0}^{3} 6 d x = 18

= 9 - \frac{45}{2} + 18

Simplify

9 - \frac{45}{2} + 18 : \frac{9}{2}

= \frac{9}{2}
