x × 1000
                                             = 500000 + 496000 x − 4000 x x + 100000(1 + x ) − 1500 x (1 + x )
                                             = 500000 + 496000 x − 4000 x x + 100000 × 1 + 100000 x − 1500 x
                                             = 500000 + 496000 x − 4000 x x + 100000 + 100000 x − 1500 x (1 + x )
                                             = 600000 + 596000 x − 4000 x x − 1500 x (1 + x )
                                             = 600000 + 596000 x − 4000 x x − 1500 x × 1 − 1500 x x
                                             = 600000 + 596000 x − 4000 x x − 1500 x − 1500 x x
                                             = 600000 + 594500 x − 4000 x x − 1500 x x
    The equation is transformed into :
     600000 + 594500 x − 4000 x x − 1500 x x = 618000
    This equation has no real solution!
