Löse

- 3 x = x^{2} + 12 : x = - \frac{3}{2} + i \frac{39}{2}, x = - \frac{3}{2} - i \frac{39}{2}

x = - \frac{3}{2} + i \frac{39}{2}, x = - \frac{3}{2} - i \frac{39}{2}

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

- 7 = - \frac{3}{x + 3}

9 = \frac{( 2 x ) ^{2}}{( 1 - x ) ( 1 - x )}

\frac{84}{r} = - 7

400 = \frac{5}{2 \times 1000 x ( 4 )}
