((a^3+3a))/((3a^2+1))= 14/13

Lösung

\frac{( a ^{3} + 3 a )}{( 3 a ^{2} + 1 )} = \frac{14}{13}

a = 2, a = \frac{8}{13} + i \frac{3 3}{13}, a = \frac{8}{13} - i \frac{3 3}{13}

(a^{3} + 3 a) \cdot 13 = (3 a^{2} + 1) \cdot 14

Löse

(a^{3} + 3 a) \cdot 13 = (3 a^{2} + 1) \cdot 14 : a = 2, a = \frac{8}{13} + i \frac{3 3}{13}, a = \frac{8}{13} - i \frac{3 3}{13}

a = 2, a = \frac{8}{13} + i \frac{3 3}{13}, a = \frac{8}{13} - i \frac{3 3}{13}

\frac{a ^{- 1}}{2} = 3
