integral from 0 to 1 of (x^2-2x+6)

\int_{0}^{1} (x^{2} - 2 x + 6) d x

\frac{16}{3}

Decimal

5.33333 \dots

Solution steps

\int_{0}^{1} x^{2} - 2 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}^{1} x^{2} d x - \int_{0}^{1} 2 x d x + \int_{0}^{1} 6 d x

\int_{0}^{1} x^{2} d x = \frac{1}{3}

\int_{0}^{1} 2 x d x = 1

\int_{0}^{1} 6 d x = 6

= \frac{1}{3} - 1 + 6

Simplify

\frac{1}{3} - 1 + 6 : \frac{16}{3}

= \frac{16}{3}
