[ 1/1 Equation]
    Work: Find the solution of equation 1/2(2m+m+2)(-m+2) = 0 .
    Question type: Equation
    Solution:Original question:
     1 ÷ 2 × (2 m + m + 2)( - m + 2) = 0
     Left side of the equation =
1
2
(2 m + m + 2)( - m + 2)
    The equation is transformed into :
     
1
2
(2 m + m + 2)( - m + 2) = 0
    Remove the bracket on the left of the equation:
     Left side of the equation =
1
2
× 2 m ( - m + 2) +
1
2
m ( - m + 2) +
1
2
× 2( - m + 2)
                                             = 1 m ( - m + 2) +
1
2
m ( - m + 2) + 1( - m + 2)
                                             = - 1 m m + 1 m × 2 +
1
2
m ( - m + 2) + 1( - m + 2)
                                             = - 1 m m + 2 m +
1
2
m ( - m + 2) + 1( - m + 2)
                                             = - 1 m m + 2 m
1
2
m m +
1
2
m × 2 + 1
                                             = - 1 m m + 2 m
1
2
m m + 1 m + 1( - m + 2)
                                             = - 1 m m + 3 m
1
2
m m + 1( - m + 2)
                                             = - 1 m m + 3 m
1
2
m m 1 m + 1 × 2
                                             = - 1 m m + 3 m
1
2
m m 1 m + 2
                                             = - 1 m m + 2 m
1
2
m m + 2
    The equation is transformed into :
      - 1 m m + 2 m
1
2
m m + 2 = 0

    After the equation is converted into a general formula, it is converted into:
    ( 3m + 2 )( m - 2 )=0
    From
        3m + 2 = 0
        m - 2 = 0

    it is concluded that::
        m1=-
2
3
        m2=2
    
    There are 2 solution(s).
