+The golden mean is the number
+\[\frac{1 + \sqrt{5}}{2},\]
+that is the root larger in modulus of
+\begin{equation} x^2 - x - 1. \end{equation}
+It is usually defined as the ratio of two lengths \(a\) and \(b\) such that
+\begin{equation*} (a+b) : a = a : b. \end{equation*}
+Let \(x\) be the ratio \( \frac{a}{b} \), we have \( \frac{a+b}{a} = 1 + \frac{1}{x} \), from which we get the equation \(x^2 = x + 1\).
