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

Lösung

erweitern

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

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

Schritte zur Lösung

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

Entferne die Klammern:

(a) = a

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

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

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

Wende Bruchregel an:

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

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

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