[ 1/1 Equation]
    Work: Find the solution of equation (1-x)(10-7x+x*x-4) = 0 .
    Question type: Equation
    Solution:Original question:
     (1 x )(107 x + x x 4) = 0
    Remove the bracket on the left of the equation:
     Left side of the equation = 1(107 x + x x 4) x (107 x + x x 4)
                                             = 1 × 101 × 7 x + 1 x x 1 × 4 x (107 x + x x 4)
                                             = 107 x + 1 x x 4 x (107 x + x x 4)
                                             = 67 x + 1 x x x (107 x + x x 4)
                                             = 67 x + 1 x x x × 10 + x × 7 x x
                                             = 613 x + 1 x x + x × 7 x x x x
    The equation is transformed into :
     613 x + 1 x x + x × 7 x x x x = 0

    After the equation is converted into a general formula, it is converted into:
    ( x - 1 )( x - 1 )( x - 6 )=0
    From
        x - 1 = 0
        x - 1 = 0
        x - 6 = 0

    it is concluded that::
        x1=1
        x2=1
        x3=6
    
    There are 3 solution(s).
