    After the equation is converted into a general formula, it is converted into:
    ( s + 8 )( s + 5 )( s + 4 )( s + 2 )=0
    From
        s + 8 = 0
        s + 5 = 0
        s + 4 = 0
        s + 2 = 0
    it is concluded that:：
        s₁=-8
        s₂=-5
        s₃=-4
        s₄=-2
    There are 4 solution(s).
