    Work: Find the solution of equation -67a^4+2a^6+308a^2 = 0 .
    Question type: Equation
    Solution:
    After the equation is converted into a general formula, it is converted into:
    ( a + √28 )( √2a +√11 )( a - 0 )( a - 0 )( √2a - √11 )( a - √28 )=0
    From
        a + √28 = 0
        √2a +√11 = 0
        a - 0 = 0
        a - 0 = 0
        √2a - √11 = 0
        a - √28 = 0
    it is concluded that:：
        a₁=-√28

a2=

-

√11 √2

a3=0

a4=0

a5=

√11 √2

        a₆=√28    
    There are 6 solution(s).
