                                             = 2148660 x − 1697400 x + 2070 x x
                                             = 451260 x + 2070 x x
    The equation is transformed into :
     451260 x + 2070 x x = 330 × 308 × 519 − 330 × 339 × 149
     Right side of the equation = 52751160 − 16668630
                                               = 36082530
    The equation is transformed into :
     451260 x + 2070 x x = 36082530

    the solutions is:
        x≈62.207984 , keep 6 decimal places    
    There are 1 solution(s).
