integral of (x-3)(sqrt(x+3))

Lösung

\int (x - 3) (x + 3) d x

Lösung

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

Schritte zur Lösung

\int (x - 3) x + 3 d x

Wende die partielle Integration an

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

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

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

Füge eine Konstante zur Lösung hinzu

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