I'm not sure I understand you correctly, but your QuadForm.pdf attachment uses the following incorrect formula: \( \begin{align} x_{1,2} = - \frac{b}{a} \pm \sqrt{\left(\frac{b}{a}\right)^2 - \frac{c}{a}} \end{align} \) This led to my comment. Example \( \begin{align} a &:= 1 \\ b &:= -5 \\ c &:= 6 \\ \\ x_{1,2} &= 5 \pm \sqrt{19} \\ \\ x_1 &\approx 0.641101 \\ x_2 &\approx 9.3589 \\ \end{align} \) \(\Rightarrow\) Incorrect BTW: The proper way to quote a post is using the ![]() (04-26-2024 06:01 AM)Thomas Klemm Wrote: PS: You missed a factor 2 in the denominator. |
