integral of (5x^2-7x+4)

Lösung

\int (5 x^{2} - 7 x + 4) d x

Lösung

\frac{5 x ^{3}}{3} - \frac{7 x ^{2}}{2} + 4 x + C

Schritte zur Lösung

\int 5 x^{2} - 7 x + 4 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 5 x^{2} d x - \int 7 x d x + \int 4 d x

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

\int 7 x d x = \frac{7 x ^{2}}{2}

\int 4 d x = 4 x

= \frac{5 x ^{3}}{3} - \frac{7 x ^{2}}{2} + 4 x

Füge eine Konstante zur Lösung hinzu

= \frac{5 x ^{3}}{3} - \frac{7 x ^{2}}{2} + 4 x + C
