erweitern ((8+3x)^2)/(16)

Lösung

erweitern

\frac{( 8 + 3 x ) ^{2}}{16}

\frac{9 x ^{2}}{16} + 3 x + 4

Schritte zur Lösung

\frac{( 8 + 3 x ) ^{2}}{16}

(8 + 3 x)^{2} = 64 + 48 x + 9 x^{2}

= \frac{64 + 48 x + 9 x ^{2}}{16}

Wende Bruchregel an:

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

\frac{64 + 48 x + 9 x ^{2}}{16} = \frac{64}{16} + \frac{48 x}{16} + \frac{9 x ^{2}}{16}

= \frac{64}{16} + \frac{48 x}{16} + \frac{9 x ^{2}}{16}

Teile die Zahlen:

\frac{64}{16} = 4

= 4 + \frac{48 x}{16} + \frac{9 x ^{2}}{16}

Teile die Zahlen:

\frac{48}{16} = 3

= 4 + 3 x + \frac{9 x ^{2}}{16}

Rewrite in standard form

= \frac{9 x ^{2}}{16} + 3 x + 4
