integral from 2 to 4 of x^2-3x+4

Solution

\int_{2}^{4} x^{2} - 3 x + 4 d x

Solution

\frac{26}{3}

+1

Decimal

8.66666 \dots

Solution steps

\int_{2}^{4} x^{2} - 3 x + 4 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}^{4} x^{2} d x - \int_{2}^{4} 3 x d x + \int_{2}^{4} 4 d x

\int_{2}^{4} x^{2} d x = \frac{56}{3}

\int_{2}^{4} 3 x d x = 18

\int_{2}^{4} 4 d x = 8

= \frac{56}{3} - 18 + 8

Simplify

\frac{56}{3} - 18 + 8 : \frac{26}{3}

= \frac{26}{3}
