which are found using the [[quadratic equation]]:

:<math>\begin{align}
\lambda_{\pm} &= {1\over 2} ( a+b) \pm {1\over 2}\sqrt{(a+b)^2-4(ab - c^2)}. </math>\\

:<math> \lambda_{\pm} &= {1\over 2} ( a+b) \pm {1\over 2}\sqrt{a^2 +2ab + b^2 -4ab + 4c^2}. </math>\\

:<math> \lambda_{\pm} &= {1\over 2} ( a+b) \pm {1\over 2}\sqrt{(a-b)^2+4c^2}. </math>
