[ 1/1 Equation]
    Work: Find the solution of equation 960 = (6-x)(200+20x) .
    Question type: Equation
    Solution:Original question:
     960 = (6 x )(200 + 20 x )
    Remove the bracket on the right of the equation:
     Right side of the equation = 6(200 + 20 x ) x (200 + 20 x )
                                               = 6 × 200 + 6 × 20 x x (200 + 20 x )
                                               = 1200 + 120 x x (200 + 20 x )
                                               = 1200 + 120 x x × 200 x × 20 x
                                               = 120080 x x × 20 x
    The equation is transformed into :
     960 = 120080 x x × 20 x

    After the equation is converted into a general formula, it is converted into:
    ( x + 6 )( x - 2 )=0
    From
        x + 6 = 0
        x - 2 = 0

    it is concluded that::
        x1=-6
        x2=2
    
    There are 2 solution(s).
