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

Lösung

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

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

Schritte zur Lösung

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

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

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

\int 5 d x = 5 x

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