erweitern (3(x+1)^2)/(x^4)

Lösung

erweitern

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

\frac{3}{x ^{2}} + \frac{6}{x ^{3}} + \frac{3}{x ^{4}}

Schritte zur Lösung

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

(x + 1)^{2} = x^{2} + 2 x + 1

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

Multipliziere aus

3 (x^{2} + 2 x + 1) : 3 x^{2} + 6 x + 3

= \frac{3 x ^{2} + 6 x + 3}{x ^{4}}

Wende Bruchregel an:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{3 x ^{2} + 6 x + 3}{x ^{4}} = \frac{3 x ^{2}}{x ^{4}} + \frac{6 x}{x ^{4}} + \frac{3}{x ^{4}}

= \frac{3 x ^{2}}{x ^{4}} + \frac{6 x}{x ^{4}} + \frac{3}{x ^{4}}
