integral of (3(x-3)^2)/(16)

Lösung

\int \frac{3 ( x - 3 ) ^{2}}{16} d x

Lösung

\frac{x ^{3}}{16} - \frac{9}{16} x^{2} + \frac{27}{16} x + C

Schritte zur Lösung

\int \frac{3 ( x - 3 ) ^{2}}{16} d x

Entferne die Konstante:

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

= \frac{3}{16} \cdot \int (x - 3)^{2} d x

Multipliziere aus

(x - 3)^{2} : x^{2} - 6 x + 9

= \frac{3}{16} \cdot \int x^{2} - 6 x + 9 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{3}{16} (\int x^{2} d x - \int 6 x d x + \int 9 d x)

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

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

\int 9 d x = 9 x

= \frac{3}{16} (\frac{x ^{3}}{3} - 3 x^{2} + 9 x)

Vereinfache

\frac{3}{16} (\frac{x ^{3}}{3} - 3 x^{2} + 9 x) : \frac{x ^{3}}{16} - \frac{9}{16} x^{2} + \frac{27}{16} x

= \frac{x ^{3}}{16} - \frac{9}{16} x^{2} + \frac{27}{16} x

= \frac{x ^{3}}{16} - \frac{9}{16} x^{2} + \frac{27}{16} x + C
