[ 1/1 Equation]
    Work: Find the solution of equation [x^2+(x^2-2x)^2]+[(3-x)^2+(x^2-2x-3)^2] = 18 .
    Question type: Equation
    Solution:
    After the equation is converted into a general formula, there is a common factor:
    ( x +0 )( x - 3 )
    From
        x + 0 = 0
        x - 3 = 0

    it is concluded that::
        x1=0
        x2=3

    Solutions that cannot be obtained by factorization:
        x3≈-0.618034 , keep 6 decimal places
        x4≈1.618034 , keep 6 decimal places
    
    There are 4 solution(s).
