[ 1/1 Equation]
    Work: Find the solution of equation 1641140.696+315089Y(237169Y^2-1129514.88+896469.6Y) = 0 .
    Question type: Equation
    Solution:
    After the equation is converted into a general formula, there is a common factor:
    ( Y - 0 )
    From
        Y - 0 = 0
    it is concluded that:：

Y1=0	, it is the incremental root of the eqution.

    Solutions that cannot be obtained by factorization:
        Y₂≈-4.776868 , keep 6 decimal places
        Y₃≈0.996986 , 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.)
