[ 1/1 Equation]
    Work: Find the solution of equation (x-3)(x-3)+1 = 2(x-3) .
    Question type: Equation
    Solution:Original question:
     ( x 3)( x 3) + 1 = 2( x 3)
    Remove the bracket on the left of the equation:
     Left side of the equation = x ( x 3)3( x 3) + 1
                                             = x x x × 33( x 3) + 1
                                             = x x 3 x 3 x + 3 × 3 + 1
                                             = x x 3 x 3 x + 9 + 1
                                             = x x 6 x + 10
    The equation is transformed into :
      x x 6 x + 10 = 2( x 3)
    Remove the bracket on the right of the equation:
     Right side of the equation = 2 x 2 × 3
                                               = 2 x 6
    The equation is transformed into :
      x x 6 x + 10 = 2 x 6

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

    it is concluded that::
        x1=4
        x2=4
    
    There are 2 solution(s).
