让我们来一起分析一下这个问题。 从几何上来看，方程的解是等号左边的曲线和等号右边的曲线的所有交点。 见上图所示 我们可以看到除了 x = 2, x=4 之外，方程应该还有另外一只解在 x < 0 的部分。 那么如何知道这个值具体是什么呢？

Using this, expressions of the form Y = XeX can be solved as X = W0(Y). You want to find the solution (s) to the equation 2x = x2. Rewrite 2x as eln (2) x and raise each side to the power of 1 2.

2^x=x^2该如何解？ 看了别人的回答，有漏解。 学到后面你会发现，如果不是纯数学，很多时候获得 数值解 就足够了.
