[ 1/1 Equation]
    Work: Find the solution of equation (20-x)(38-x) = 544 .
    Question type: Equation
    Solution:Original question:
     (20 x )(38 x ) = 544
    Remove the bracket on the left of the equation:
     Left side of the equation = 20(38 x ) x (38 x )
                                             = 20 × 3820 x x (38 x )
                                             = 76020 x x (38 x )
                                             = 76020 x x × 38 + x x
                                             = 76058 x + x x
    The equation is transformed into :
     76058 x + x x = 544

    After the equation is converted into a general formula, it is converted into:
    ( x - 4 )( x - 54 )=0
    From
        x - 4 = 0
        x - 54 = 0

    it is concluded that::
        x1=4
        x2=54
    
    There are 2 solution(s).
