[ 1/2 Equation]
    Work: Find the solution of equation x^3-3*3.14*x*0.6053*10^3/(0.06544*3.31)+2*3.14*sqrt(1-0.85^2)*0.6053 = 0 .
    Question type: Equation
    Solution:
    After the equation is converted into a general formula, there is a common factor:
    ( x - 0 )
    From
        x - 0 = 0
    it is concluded that:：
        x₁=0, it is the incremental root of the eqution.
    Solutions that cannot be obtained by factorization:
        x₂≈-162.246467 , keep 6 decimal places
        x₃≈162.246391 , 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.)
