[ 1/1 Equation]
    Work: Find the solution of equation 1-1/(1+r)^12 = 11412*r/951 .
    Question type: Equation
    Solution:
    After the equation is converted into a general formula, there is a common factor:
    ( r - 0 )( r - 0 )
    From
        r - 0 = 0
        r - 0 = 0
    it is concluded that:：

r1=0

r2=0

    Solutions that cannot be obtained by factorization:
        r₃≈-1.772142 , keep 6 decimal places    
    There are 3 solution(s).
