integral of ((6x^2+2sqrt(x))/(2sqrt(x)))

Lösung

\int (\frac{6 x ^{2} + 2 x}{2 x}) d x

Lösung

\frac{1}{5} (6 x^{\frac{5}{2}} + 5 x) + C

Schritte zur Lösung

\int \frac{6 x ^{2} + 2 x}{2 x} d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{2} \cdot \int \frac{6 x ^{2} + 2 x}{x} d x

\frac{6 x ^{2} + 2 x}{x} : 6 x^{\frac{3}{2}} + 2

= \frac{1}{2} \cdot \int 6 x^{\frac{3}{2}} + 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

= \frac{1}{2} (\int 6 x^{\frac{3}{2}} d x + \int 2 d x)

\int 6 x^{\frac{3}{2}} d x = \frac{12}{5} x^{\frac{5}{2}}

\int 2 d x = 2 x

= \frac{1}{2} (\frac{12}{5} x^{\frac{5}{2}} + 2 x)

Vereinfache

\frac{1}{2} (\frac{12}{5} x^{\frac{5}{2}} + 2 x) : \frac{1}{5} (6 x^{\frac{5}{2}} + 5 x)

= \frac{1}{5} (6 x^{\frac{5}{2}} + 5 x)
