[ 1/1 Equation]
    Work: Find the solution of equation x*(x+2)*(x+4)*(x+6) = 3465 .
    Question type: Equation
    Solution:Original question:
      x ( x + 2)( x + 4)( x + 6) = 3465
    Remove the bracket on the left of the equation:
     Left side of the equation = x x ( x + 4)( x + 6) + x × 2( x + 4)( x + 6)
                                             = x x x ( x + 6) + x x × 4( x + 6) + x × 2( x + 4)( x + 6)
                                             = x x x x + x x x × 6 + x x × 4( x + 6)
                                             = x x x x + x x x × 6 + x x × 4 x
                                             = x x x x + x x x × 6 + x x × 4 x
                                             = x x x x + x x x × 6 + x x × 4 x
                                             = x x x x + x x x × 6 + x x × 4 x
                                             = x x x x + x x x × 6 + x x × 4 x
                                             = x x x x + x x x × 6 + x x × 4 x
                                             = x x x x + x x x × 6 + x x × 4 x
                                             = x x x x + x x x × 6 + x x × 4 x
    The equation is transformed into :
      x x x x + x x x × 6 + x x × 4 x = 3465

    After the equation is converted into a general formula, it is converted into:
    ( x + 11 )( x - 5 )=0
    From
        x + 11 = 0
        x - 5 = 0
    it is concluded that:：
        x1=-11
        x2=5    
    There are 2 solution(s).
