integral of 4x^3-20x^2+8x+32

Lösung

\int 4 x^{3} - 20 x^{2} + 8 x + 32 d x

x^{4} - \frac{20 x ^{3}}{3} + 4 x^{2} + 32 x + C

Schritte zur Lösung

\int 4 x^{3} - 20 x^{2} + 8 x + 32 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 4 x^{3} d x - \int 20 x^{2} d x + \int 8 x d x + \int 32 d x

\int 4 x^{3} d x = x^{4}

\int 20 x^{2} d x = \frac{20 x ^{3}}{3}

\int 8 x d x = 4 x^{2}

\int 32 d x = 32 x

= x^{4} - \frac{20 x ^{3}}{3} + 4 x^{2} + 32 x
