[ 1/1 Equation]
    Work: Find the solution of equation x^(30-8)*(x-1)^2*(x+1)^2*(x^4-(30-1)*x^2+30-7) = 0 .
    Question type: Equation
    Solution:
    After the equation is converted into a general formula, there is a common factor:
    ( x - 0 )( x - 0 )( x - 1 )( x - 1 )
    From
        x - 0 = 0
        x - 0 = 0
        x - 1 = 0
        x - 1 = 0
    it is concluded that:：

x1=0

x2=0

x3=1

x4=1

    Solutions that cannot be obtained by factorization:
        x₅≈-5.308854 , keep 6 decimal places
        x₆≈-0.903365 , keep 6 decimal places
        x₇≈0.903365 , keep 6 decimal places
        x₈≈5.308854 , keep 6 decimal places    
    There are 8 solution(s).
