[ 1/1 Equation]
    Work: Find the solution of equation x(77-4x+3) = 300 .
    Question type: Equation
    Solution:Original question:
      x (774 x + 3) = 300
    Remove the bracket on the left of the equation:
     Left side of the equation = x × 77 x × 4 x + x × 3
                                             = 80 x x × 4 x
    The equation is transformed into :
     80 x x × 4 x = 300

    After the equation is converted into a general formula, it is converted into:
    ( x - 5 )( x - 15 )=0
    From
        x - 5 = 0
        x - 15 = 0

    it is concluded that::
        x1=5
        x2=15
    
    There are 2 solution(s).
