[ 1/1 Equation]
    Work: Find the solution of equation -ln(1-x^2） = ln2 .
    Question type: Equation
    Solution:
    After the equation is converted into a general formula, it is converted into:
    ( √2x +1 )( √2x - 1 )=0
    From
        √2x +1 = 0
        √2x - 1 = 0
    it is concluded that:：

x1=

-

1 √2
