[ 1/1 Equation]
    Work: Find the solution of equation 2126153*((1+x)^-25) = (50000*((1+x)^15-1)/x)*(1+x)^7 .
    Question type: Equation
    Solution:
    After the equation is converted into a general formula, there is a common factor:
    ( x + 1 )
    From
        x + 1 = 0

    it is concluded that::
        x1=-1, it is the incremental root of the eqution.

    Solutions that cannot be obtained by factorization:
        x2≈-2.094898 , keep 6 decimal places
        x3≈0.026905 , keep 6 decimal places
    
    There are 3 solution(s).

    There is(are) 1 additive root(s) and 2 real solutions.
(Note:additive root, generated by computer, but not suitable for this equation.)
