integral of (x+2)sqrt(x+4)

Lösung

\int (x + 2) x + 4 d x

\frac{2}{3} (x + 2) (x + 4)^{\frac{3}{2}} - \frac{4}{15} (x + 4)^{\frac{5}{2}} + C

Schritte zur Lösung

\int (x + 2) x + 4 d x

Wende die partielle Integration an

= \frac{2}{3} (x + 2) (x + 4)^{\frac{3}{2}} - \int \frac{2}{3} (x + 4)^{\frac{3}{2}} d x

\int \frac{2}{3} (x + 4)^{\frac{3}{2}} d x = \frac{4}{15} (x + 4)^{\frac{5}{2}}

= \frac{2}{3} (x + 2) (x + 4)^{\frac{3}{2}} - \frac{4}{15} (x + 4)^{\frac{5}{2}}
