    After the equation is converted into a general formula, there is a common factor:
    ( 5x - √737004 )
    From
        5x - √737004 = 0

    it is concluded that::
        x1=
√737004

    Solutions that cannot be obtained by factorization:
        x2≈-171.697874 , keep 6 decimal places
    
    There are 2 solution(s).
