cx^2+12x+c=0

Lösung

c x^{2} + 12 x + c = 0

x = \frac{- 6 + - c ^{2} + 36}{c}, x = - \frac{- c ^{2} + 36 + 6}{c}; c \neq = 0

Schritte zur Lösung

c x^{2} + 12 x + c = 0

Löse mit der quadratischen Formel

x_{1, 2} = \frac{- 12 \pm 1 2 ^{2} - 4 cc}{2 c}

Vereinfache

1 2^{2} - 4 cc : 2 36 - c^{2}

x_{1, 2} = \frac{- 12 \pm 2 36 - c ^{2}}{2 c}; c \neq = 0

Trenne die Lösungen

x_{1} = \frac{- 12 + 2 36 - c ^{2}}{2 c}, x_{2} = \frac{- 12 - 2 36 - c ^{2}}{2 c}

x = \frac{- 12 + 2 36 - c ^{2}}{2 c} : \frac{- 6 + - c ^{2} + 36}{c}

x = \frac{- 12 - 2 36 - c ^{2}}{2 c} : - \frac{- c ^{2} + 36 + 6}{c}

Die Lösungen für die quadratische Gleichung sind:

x = \frac{- 6 + - c ^{2} + 36}{c}, x = - \frac{- c ^{2} + 36 + 6}{c}; c \neq = 0

7 x + 1 = 3 x^{2} - 2 x

x^{2} = 0.49

(2 x + 5)^{2} - 33 = - 8
