The original equation can be changed to m (m-1) x2-(2m2-1) x+m (m+1) = 0.

=[m(m- 1)]x？ -【m？ +(m？ - 1)]x+m(m+ 1)

Cross multiplication: [MX-(m+1)] [(m-1) x-m] = 0.

Mx-m- 1=0 or (m- 1)x-m=0.

Mx=m+ 1 or (m-1) x = m.

When m=0, the solution of the original equation is x=0.

When m= 1, the solution of the original equation is x=2.

When m≠0 and m≠ 1, x=(m+ 1)/m or x=m/(m- 1).
