Schritte zur Lösung

- 0.0013 x^{2} + x + 13 = 0

Löse mit der quadratischen Formel

x_{1, 2} = \frac{- 1 \pm 1 ^{2} - 4 ( - 0.0013 ) \cdot 13}{2 ( - 0.0013 )}

1^{2} - 4 (- 0.0013) \cdot 13 = 1.0676

x_{1, 2} = \frac{- 1 \pm 1.0676}{2 ( - 0.0013 )}

Trenne die Lösungen

x_{1} = \frac{- 1 + 1.0676}{2 ( - 0.0013 )}, x_{2} = \frac{- 1 - 1.0676}{2 ( - 0.0013 )}

x = \frac{- 1 + 1.0676}{2 ( - 0.0013 )} : - \frac{- 1 + 1.0676}{0.0026}

x = \frac{- 1 - 1.0676}{2 ( - 0.0013 )} : \frac{1 + 1.0676}{0.0026}

Die Lösungen für die quadratische Gleichung sind:

x = - \frac{- 1 + 1.0676}{0.0026}, x = \frac{1 + 1.0676}{0.0026}
