[ 1/1 Equation]
    Work: Find the solution of equation 2(1000-200m)(1+0.5m)+8*500(1+m) = 14400 .
    Question type: Equation
    Solution:Original question:
     2(1000200 m )(1 +

m ) + 8 × 500(1 + m ) = 14400
     Left side of the equation = 2(1000200 m )(1 +

2
m ) + 4000(1 + m )
    The equation is transformed into :
     2(1000200 m )(1 +

m ) + 4000(1 + m ) = 14400
    Remove the bracket on the left of the equation:
     Left side of the equation = 2 × 1000(1 +

m + 4000(1 + m )
                                             = 2000 + 1000 m 400 m 200 m m + 4000(1 + m )
                                             = 2000 + 600 m 200 m m + 4000(1 + m )
                                             = 2000 + 600 m 200 m m + 4000 × 1 + 4000 m
                                             = 2000 + 600 m 200 m m + 4000 + 4000 m
                                             = 6000 + 4600 m 200 m m
    The equation is transformed into :
     6000 + 4600 m 200 m m = 14400

    After the equation is converted into a general formula, it is converted into:
    ( m - 2 )( m - 21 )=0
    From
        m - 2 = 0
        m - 21 = 0

    it is concluded that::
        m1=2
        m2=21
    
    There are 2 solution(s).
