[ 1/1 Equation]
    Work: Find the solution of equation (x+0)*(x+4)*(x+8) = 0 .
    Question type: Equation
    Solution:Original question:
     ( x + 0)( x + 4)( x + 8) = 0
    Remove the bracket on the left of the equation:
     Left side of the equation = x ( x + 4)( x + 8) + 0( x + 4)( x + 8)
                                             = x x ( x + 8) + x × 4( x + 8) + 0( x + 4)( x + 8)
                                             = x x x + x x × 8 + x × 4( x + 8) + 0( x + 4)( x + 8)
                                             = x x x + x x × 8 + x × 4 x + x × 4 × 8
                                             = x x x + x x × 8 + x × 4 x + x × 32 + 0
                                             = x x x + x x × 8 + x × 4 x + 32 x + 0
                                             = x x x + x x × 8 + x × 4 x + 32 x + 0
                                             = x x x + x x × 8 + x × 4 x + 32 x + 0
                                             = x x x + x x × 8 + x × 4 x + 32 x + 0
                                             = x x x + x x × 8 + x × 4 x + 32 x + 0
                                             = x x x + x x × 8 + x × 4 x + 32 x + 0
                                             = x x x + x x × 8 + x × 4 x + 32 x + 0
                                             = x x x + x x × 8 + x × 4 x + 32 x + 0
    The equation is transformed into :
      x x x + x x × 8 + x × 4 x + 32 x + 0 = 0

    After the equation is converted into a general formula, it is converted into:
    ( x + 8 )( x + 4 )( x +0 )=0
    From
        x + 8 = 0
        x + 4 = 0
        x + 0 = 0

    it is concluded that::
        x1=-8
        x2=-4
        x3=0
    
    There are 3 solution(s).
