[ 1/1 Equation]
    Work: Find the solution of equation x(x+1)+x+1 = 64 .
    Question type: Equation
    Solution:Original question:
      x ( x + 1) + x + 1 = 64
    Remove the bracket on the left of the equation:
     Left side of the equation = x x + x × 1 + x + 1
                                             = x x + 2 x + 1
    The equation is transformed into :
      x x + 2 x + 1 = 64

    After the equation is converted into a general formula, it is converted into:
    ( x + 9 )( x - 7 )=0
    From
        x + 9 = 0
        x - 7 = 0

    it is concluded that::
        x1=-9
        x2=7
    
    There are 2 solution(s).
