Lösung

erweitern

\frac{72 + \frac{x ^{2}}{2}}{2}

\frac{x ^{2}}{4} + 36

Schritte zur Lösung

\frac{72 + \frac{x ^{2}}{2}}{2}

Füge

72 + \frac{x ^{2}}{2}

zusammen:

\frac{144 + x ^{2}}{2}

= \frac{\frac{144 + x ^{2}}{2}}{2}

Wende Bruchregel an:

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

= \frac{144 + x ^{2}}{2 \cdot 2}

Multipliziere die Zahlen:

2 \cdot 2 = 4

= \frac{144 + x ^{2}}{4}

Wende Bruchregel an:

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

\frac{144 + x ^{2}}{4} = \frac{144}{4} + \frac{x ^{2}}{4}

= \frac{144}{4} + \frac{x ^{2}}{4}

Teile die Zahlen:

\frac{144}{4} = 36

= 36 + \frac{x ^{2}}{4}

Rewrite in standard form

= \frac{x ^{2}}{4} + 36
