[ 1/1 Equation]
    Work: Find the solution of equation (x+5)(x+2)+66 = 2x+66 .
    Question type: Equation
    Solution:Original question:
     ( x + 5)( x + 2) + 66 = 2 x + 66
    Remove the bracket on the left of the equation:
     Left side of the equation = x ( x + 2) + 5( x + 2) + 66
                                             = x x + x × 2 + 5( x + 2) + 66
                                             = x x + 2 x + 5 x + 5 × 2 + 66
                                             = x x + 2 x + 5 x + 10 + 66
                                             = x x + 7 x + 76
    The equation is transformed into :
      x x + 7 x + 76 = 2 x + 66
    This equation has no real solution!
