Schritte zur Lösung

0.825 x^{2} + 0.15 x - 0.003621753 = 0

Löse mit der quadratischen Formel

x_{1, 2} = \frac{- 0.15 \pm 0.1 5 ^{2} - 4 \cdot 0.825 ( - 0.003621753 )}{2 \cdot 0.825}

0.1 5^{2} - 4 \cdot 0.825 (- 0.003621753) = 0.0344517849

x_{1, 2} = \frac{- 0.15 \pm 0.0344517849}{2 \cdot 0.825}
