integral of x(15x+4)

Lösung

\int x (15 x + 4) d x

Lösung

5 x^{3} + 2 x^{2} + C

Schritte zur Lösung

\int x (15 x + 4) d x

Multipliziere aus

x (15 x + 4) : 15 x^{2} + 4 x

= \int 15 x^{2} + 4 x 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

= \int 15 x^{2} d x + \int 4 x d x

\int 15 x^{2} d x = 5 x^{3}

\int 4 x d x = 2 x^{2}

= 5 x^{3} + 2 x^{2}

Füge eine Konstante zur Lösung hinzu

= 5 x^{3} + 2 x^{2} + C
