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

Solution

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

Solution

\frac{4}{3}

+1

Decimal

1.33333 \dots

Solution steps

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

\int_{2}^{3} x^{2} d x = \frac{19}{3}

\int_{2}^{3} 2 x d x = 5

= \frac{19}{3} - 5

Simplify

\frac{19}{3} - 5 : \frac{4}{3}

= \frac{4}{3}
