[ 1/1 Equation]
    Work: Find the solution of equation a^(2)+3a-4 = 0 .
    Question type: Equation
    Solution:
    After the equation is converted into a general formula, it is converted into:
    ( a + 4 )( a - 1 )=0
    From
        a + 4 = 0
        a - 1 = 0

    it is concluded that::
        a1=-4
        a2=1
    
    There are 2 solution(s).
