[ 1/1 Equation]
    Work: Find the solution of equation [m(m+2)]/(m-1) = 0 .
    Question type: Equation
    Solution:Original question:

(

m

(

m

+

2

)

)

÷

(

m

−

1

)

=

0

Multiply both sides of the equation by:

(

m

−

1

)

(

m

(

m

+

2

)

)

=

0

    Remove a bracket on the left of the equation:：

m

(

m

+

2

)

=

0

    Remove a bracket on the left of the equation:

m

m

+

m

×

2

=

0

    After the equation is converted into a general formula, it is converted into:
    ( m + 2 )( m - 0 )=0
    From
        m + 2 = 0
        m - 0 = 0
    it is concluded that:：
        m₁=-2
        m₂=0    
    There are 2 solution(s).
