[ 1/1 Equation]
    Work: Find the solution of equation 5+(x+1)*(x+2)*(x+3) = 0 .
    Question type: Equation
    Solution:Original question:
     5 + ( x + 1)( x + 2)( x + 3) = 0
    Remove the bracket on the left of the equation:
     Left side of the equation = 5 + x ( x + 2)( x + 3) + 1( x + 2)( x + 3)
                                             = 5 + x x ( x + 3) + x × 2( x + 3) + 1( x + 2)( x + 3)
                                             = 5 + x x x + x x × 3 + x × 2( x + 3) + 1( x + 2)
                                             = 5 + x x x + x x × 3 + x × 2 x + x × 2
                                             = 5 + x x x + x x × 3 + x × 2 x + x × 6
                                             = 5 + x x x + x x × 3 + x × 2 x + 6 x
                                             = 5 + x x x + x x × 3 + x × 2 x + 6 x
                                             = 5 + x x x + x x × 3 + x × 2 x + 6 x
                                             = 5 + x x x + x x × 3 + x × 2 x + 6 x
                                             = 5 + x x x + x x × 3 + x × 2 x + 9 x
                                             = 5 + x x x + x x × 3 + x × 2 x + 9 x
                                             = 5 + x x x + x x × 3 + x × 2 x + 9 x
                                             = 11 + x x x + x x × 3 + x × 2 x + 11 x
    The equation is transformed into :
     11 + x x x + x x × 3 + x × 2 x + 11 x = 0

    
        x≈-3.904161 , keep 6 decimal places
    
    There are 1 solution(s).
