integral of (6x^3+5x^2-4)/(x^2)

Lösung

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

Lösung

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

Schritte zur Lösung

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

Multipliziere aus

\frac{6 x ^{3} + 5 x ^{2} - 4}{x ^{2}} : 6 x + 5 - \frac{4}{x ^{2}}

= \int 6 x + 5 - \frac{4}{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

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

\int 6 x d x = 3 x^{2}

\int 5 d x = 5 x

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

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

Vereinfache

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