[ 1/1 Equation]
    Work: Find the solution of equation (x+1)(x十2)(x+3)(x十4)十1 = 0 .
    Question type: Equation
    Solution:Original question:
     ( x + 1)( x + 2)( x + 3)( x + 4) + 1 = 0
    Remove the bracket on the left of the equation:
     Left side of the equation = x ( x + 2)( x + 3)( x + 4) + 1( x + 2)( x + 3)( x + 4) + 1
                                             = x x ( x + 3)( x + 4) + x × 2( x + 3)( x + 4) + 1( x + 2)( x + 3)( x + 4)
                                             = x x x ( x + 4) + x x × 3( x + 4) + x × 2( x + 3)( x + 4)
                                             = x x x x + x x x × 4 + x x × 3( x + 4)
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x
                                             = x x x x + x x x × 4 + x x × 3 x

    After the equation is converted into a general formula, it is converted into:
    ( 500000x + 1809017 )( 500000x + 1809017 )( 500000x + 690983 )( 500000x + 690983 )=0
    From
        500000x + 1809017 = 0
        500000x + 1809017 = 0
        500000x + 690983 = 0
        500000x + 690983 = 0
    it is concluded that:：
        x1=-
1809017
500000
        x2=-
1809017
500000
        x3=-
690983
500000
        x4=-
690983
500000
    
    There are 4 solution(s).
