\int \frac{( 12 x + 1 )}{4 x - 3} d x

\frac{1}{2} ((4 x - 3)^{\frac{3}{2}} + 10 4 x - 3) + C

Schritte zur Lösung

\int \frac{12 x + 1}{4 x - 3} d x

Wende U-Substitution an

= \int \frac{3 u ^{2} + 10}{2} d u

Entferne die Konstante:

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

= \frac{1}{2} \cdot \int 3 u^{2} + 10 d u

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 3 u^{2} d u + \int 10 d u)

\int 3 u^{2} d u = u^{3}

\int 10 d u = 10 u

= \frac{1}{2} (u^{3} + 10 u)

Setze in

u = 4 x - 3

ein

= \frac{1}{2} ((4 x - 3)^{3} + 10 4 x - 3)

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

= \frac{1}{2} ((4 x - 3)^{\frac{3}{2}} + 10 4 x - 3)

= \frac{1}{2} ((4 x - 3)^{\frac{3}{2}} + 10 4 x - 3) + C

\int 3 x^{2} - 3 x (2 x - 3) d x

\int \frac{1}{( x ^{2} + 2 x + 10 ) ^{2}} d x

\int \frac{4 x ^{3}}{( x ^{2} + 1 ) ^{3}} d x

\int \frac{x}{( 25 + x ^{2} ) ^{3}} d x
