[ 1/1 Equation]
    Work: Find the solution of equation (x-2)(x-2)(x-2)-3(x-2) = 2 .
    Question type: Equation
    Solution:Original question:
     ( x 2)( x 2)( x 2)3( x 2) = 2
    Remove the bracket on the left of the equation:
     Left side of the equation = x ( x 2)( x 2)2( x 2)( x 2)3( x 2)
                                             = x x ( x 2) x × 2( x 2)2( x 2)( x 2)3( x 2)
                                             = x x x x x × 2 x × 2( x 2)2( x 2)( x 2)
                                             = x x x x x × 2 x × 2 x + x × 2 × 2
                                             = x x x x x × 2 x × 2 x + x × 42
                                             = x x x x x × 2 x × 2 x + 4 x 2
                                             = x x x x x × 2 x × 2 x + 4 x 2
                                             = x x x x x × 2 x × 2 x + 4 x 2
                                             = x x x x x × 2 x × 2 x + 4 x 2
                                             = x x x x x × 2 x × 2 x + 8 x 2
                                             = x x x x x × 2 x × 2 x + 8 x 2
                                             = x x x x x × 2 x × 2 x + 8 x 2
                                             = x x x x x × 2 x × 2 x + 12 x 2
                                             = x x x x x × 2 x × 2 x + 12 x 2
                                             = x x x x x × 2 x × 2 x + 12 x 2
                                             = x x x x x × 2 x × 2 x + 9 x 2
    The equation is transformed into :
      x x x x x × 2 x × 2 x + 9 x 2 = 2

    After the equation is converted into a general formula, it is converted into:
    ( x - 1 )( x - 1 )( x - 4 )=0
    From
        x - 1 = 0
        x - 1 = 0
        x - 4 = 0

    it is concluded that::
        x1=1
        x2=1
        x3=4
    
    There are 3 solution(s).
