    Work: Find the solution of equation x(x+50)(x+250) = (x+50)(x+5)(x+250)+x(x+250)(x+50)+x(x+50)(x+50) .
    Question type: Equation
    Solution:Original question:
      x ( x + 50)( x + 250) = ( x + 50)( x + 5)( x + 250) + x ( x + 250)( x + 50) + x ( x + 50)( x + 50)
    Remove the bracket on the left of the equation:
     Left side of the equation = x x ( x + 250) + x × 50( x + 250)
                                             = x x x + x x × 250 + x × 50( x + 250)
                                             = x x x + x x × 250 + x × 50 x + x × 50 × 250
                                             = x x x + x x × 250 + x × 50 x + x × 12500
    The equation is transformed into :
      x x x + x x × 250 + x × 50 x + 12500 x = ( x + 50)( x + 5)( x + 250) + x ( x + 250)( x + 50) + x ( x + 50)( x + 50)
    Remove the bracket on the right of the equation:
     Right side of the equation = x ( x + 5)( x + 250) + 50( x + 5)( x + 250) + x ( x + 250)( x + 50) + x ( x + 50)( x + 50)
                                               = x x ( x + 250) + x × 5( x + 250) + 50( x + 5)( x + 250) + x ( x + 250)( x + 50)
                                               = x x x + x x × 250 + x × 5( x + 250) + 50( x + 5)( x + 250)
                                               = x x x + x x × 250 + x × 5 x + x × 5 × 250
                                               = x x x + x x × 250 + x × 5 x + x × 1250 + 50
                                               = x x x + x x × 250 + x × 5 x + 1250 x + 50
                                               = x x x + x x × 250 + x × 5 x + 1250 x + 50
                                               = x x x + x x × 250 + x × 5 x + 1250 x + 50
                                               = x x x + x x × 250 + x × 5 x + 1250 x + 50
                                               = x x x + x x × 250 + x × 5 x + 13750 x + 50
                                               = x x x + x x × 250 + x × 5 x + 13750 x + 50
                                               = x x x + x x × 250 + x × 5 x + 13750 x + 50
                                               = x x x + x x × 250 + x × 5 x + 14000 x + 50
                                               = x x x + x x × 250 + x × 5 x + 14000 x + 50
                                               = x x x + x x × 250 + x × 5 x + 14000 x + 50
                                               = x x x + x x × 250 + x × 5 x + 14000 x + 50
                                               = x x x + x x × 250 + x × 5 x + 14000 x + 50
                                               = x x x + x x × 250 + x × 5 x + 26500 x + 50
                                               = x x x + x x × 250 + x × 5 x + 26500 x + 50
                                               = x x x + x x × 250 + x × 5 x + 26500 x + 50

    After the equation is converted into a general formula, there is a common factor:
    ( x + 50 )
    From
        x + 50 = 0

    it is concluded that::
        x1=-50
    Solutions that cannot be obtained by factorization:
        x2≈-148.285148 , keep 6 decimal places
        x3≈-4.214852 , keep 6 decimal places
    
    There are 3 solution(s).
