integral of 5xsqrt(5-x^2)

\int 5 x 5 - x^{2} d x

- \frac{5}{3} (5 - x^{2})^{\frac{3}{2}} + C

Solution steps

\int 5 x 5 - x^{2} d x

Take the constant out:

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

= 5 \cdot \int x 5 - x^{2} d x

Apply u-substitution

= 5 \cdot \int - \frac{u}{2} d u

Take the constant out:

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

= 5 (- \frac{1}{2} \cdot \int u d u)

Apply the Power Rule

= 5 (- \frac{1}{2} \cdot \frac{2}{3} u^{\frac{3}{2}})

Substitute back

u = 5 - x^{2}

= 5 (- \frac{1}{2} \cdot \frac{2}{3} (5 - x^{2})^{\frac{3}{2}})

Simplify

5 (- \frac{1}{2} \cdot \frac{2}{3} (5 - x^{2})^{\frac{3}{2}}) : - \frac{5}{3} (5 - x^{2})^{\frac{3}{2}}

= - \frac{5}{3} (5 - x^{2})^{\frac{3}{2}}

Add a constant to the solution

= - \frac{5}{3} (5 - x^{2})^{\frac{3}{2}} + C
