integral from 2 to 4 of x^2+3

Solution

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

Solution

\frac{74}{3}

+1

Decimal Notation

24.66666 \dots

Solution steps

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

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

\int_{2}^{4} 3 d x = 6

= \frac{56}{3} + 6

Simplify

\frac{56}{3} + 6 : \frac{74}{3}

= \frac{74}{3}
