[ 1/1 Equation]
    Work: Find the solution of equation (y-6)(y-2) = 1 .
    Question type: Equation
    Solution:Original question:
     ( y 6)( y 2) = 1
    Remove the bracket on the left of the equation:
     Left side of the equation = y ( y 2)6( y 2)
                                             = y y y × 26( y 2)
                                             = y y 2 y 6 y + 6 × 2
                                             = y y 2 y 6 y + 12
                                             = y y 8 y + 12
    The equation is transformed into :
      y y 8 y + 12 = 1

    The solution of the equation:
        y1≈1.763932 , keep 6 decimal places
        y2≈6.236068 , keep 6 decimal places
    
    There are 2 solution(s).
