integral of (6x^2)(2x^3+1)^2

Lösung

\int (6 x^{2}) (2 x^{3} + 1)^{2} d x

Lösung

6 (\frac{4 x ^{9}}{9} + \frac{2 x ^{6}}{3} + \frac{x ^{3}}{3}) + C

Schritte zur Lösung

\int 6 x^{2} (2 x^{3} + 1)^{2} d x

Entferne die Konstante:

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

= 6 \cdot \int x^{2} (2 x^{3} + 1)^{2} d x

x^{2} (2 x^{3} + 1)^{2} : 4 x^{8} + 4 x^{5} + x^{2}

= 6 \cdot \int 4 x^{8} + 4 x^{5} + x^{2} d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= 6 (\int 4 x^{8} d x + \int 4 x^{5} d x + \int x^{2} d x)

\int 4 x^{8} d x = \frac{4 x ^{9}}{9}

\int 4 x^{5} d x = \frac{2 x ^{6}}{3}

\int x^{2} d x = \frac{x ^{3}}{3}

= 6 (\frac{4 x ^{9}}{9} + \frac{2 x ^{6}}{3} + \frac{x ^{3}}{3})

Füge eine Konstante zur Lösung hinzu

= 6 (\frac{4 x ^{9}}{9} + \frac{2 x ^{6}}{3} + \frac{x ^{3}}{3}) + C
