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

x^{6} + x^{5} + \frac{x ^{4}}{4} + 2 x^{3} + x^{2} + 1

Schritte zur Lösung

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

(2 + x^{2} + 2 x^{3})^{2} = 8 x^{3} + 4 x^{5} + 4 x^{6} + 4 x^{2} + x^{4} + 4

= \frac{8 x ^{3} + 4 x ^{5} + 4 x ^{6} + 4 x ^{2} + x ^{4} + 4}{4}

Wende Bruchregel an:

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

\frac{8 x ^{3} + 4 x ^{5} + 4 x ^{6} + 4 x ^{2} + x ^{4} + 4}{4} = \frac{8 x ^{3}}{4} + \frac{4 x ^{5}}{4} + \frac{4 x ^{6}}{4} + \frac{4 x ^{2}}{4} + \frac{x ^{4}}{4} + \frac{4}{4}

= \frac{8 x ^{3}}{4} + \frac{4 x ^{5}}{4} + \frac{4 x ^{6}}{4} + \frac{4 x ^{2}}{4} + \frac{x ^{4}}{4} + \frac{4}{4}

Wende Regel an

\frac{a}{a} = 1

\frac{4}{4} = 1

= \frac{8 x ^{3}}{4} + \frac{4 x ^{5}}{4} + \frac{4 x ^{6}}{4} + \frac{4 x ^{2}}{4} + \frac{x ^{4}}{4} + 1

\frac{8 x ^{3}}{4} = 2 x^{3}

\frac{4 x ^{5}}{4} = x^{5}

\frac{4 x ^{6}}{4} = x^{6}

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

= 2 x^{3} + x^{5} + x^{6} + x^{2} + \frac{x ^{4}}{4} + 1

Rewrite in standard form

= x^{6} + x^{5} + \frac{x ^{4}}{4} + 2 x^{3} + x^{2} + 1

e x p an d \frac{2}{3} (6 x - 15 = 18)
