[ 1/1 Equation]
    Work: Find the solution of equation (x-8)[100-10(x-10)] = 0 .
    Question type: Equation
    Solution:Original question:
     ( x 8)(10010( x 10)) = 0
    Remove the bracket on the left of the equation:
     Left side of the equation = x (10010( x 10))8(10010( x 10))
                                             = x × 100 x × 10( x 10)8(10010( x 10))
                                             = 100 x x × 10 x + x × 10 × 108(10010( x 10))
                                             = 100 x x × 10 x + x × 1008(10010( x 10))
                                             = 200 x x × 10 x 8(10010( x 10))
                                             = 200 x x × 10 x 8 × 100 + 8 × 10( x 10)
                                             = 200 x x × 10 x 800 + 80( x 10)
                                             = 200 x x × 10 x 800 + 80 x 80 × 10
                                             = 200 x x × 10 x 800 + 80 x 800
                                             = 280 x x × 10 x 1600
    The equation is transformed into :
     280 x x × 10 x 1600 = 0

    After the equation is converted into a general formula, it is converted into:
    ( x - 8 )( x - 20 )=0
    From
        x - 8 = 0
        x - 20 = 0

    it is concluded that::
        x1=8
        x2=20
    
    There are 2 solution(s).
