integral from 0 to 2 of sqrt(2x+5)

\int_{0}^{2} 2 x + 5 d x

\frac{27 - 5 5}{3}

Decimal

5.27322 \dots

Solution steps

\int_{0}^{2} 2 x + 5 d x

Apply u-substitution

= \int_{5}^{9} \frac{u}{2} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{2} \cdot \int_{5}^{9} u d u

Apply the Power Rule

= \frac{1}{2} [\frac{2}{3} u^{\frac{3}{2}}]_{5}^{9}

Compute the boundaries:

18 - \frac{10 5}{3}

= \frac{1}{2} (18 - \frac{10 5}{3})

Simplify

= \frac{27 - 5 5}{3}
