[ 1/1 Equation]
    Work: Find the solution of equation x^2+1/x^2+2x+2/x = 6 .
    Question type: Equation
    Solution:
    After the equation is converted into a general formula, there is a common factor:
    ( x - 1 )( x - 1 )
    From
        x - 1 = 0
        x - 1 = 0
    it is concluded that:：

x1=1

x2=1

    Solutions that cannot be obtained by factorization:
        x₃≈-3.732051 , keep 6 decimal places
        x₄≈-0.267949 , keep 6 decimal places    
    There are 4 solution(s).
