[ 1/1 Equation]
    Work: Find the solution of equation -2k+6 = (2k-6)*(4k-6) .
    Question type: Equation
    Solution:Original question:
      - 2 k + 6 = (2 k 6)(4 k 6)
    Remove the bracket on the right of the equation:
     Right side of the equation = 2 k (4 k 6)6(4 k 6)
                                               = 2 k × 4 k 2 k × 66(4 k 6)
                                               = 8 k k 12 k 6(4 k 6)
                                               = 8 k k 12 k 6 × 4 k + 6 × 6
                                               = 8 k k 12 k 24 k + 36
                                               = 8 k k 36 k + 36
    The equation is transformed into :
      - 2 k + 6 = 8 k k 36 k + 36

    After the equation is converted into a general formula, it is converted into:
    ( 4k - 5 )( k - 3 )=0
    From
        4k - 5 = 0
        k - 3 = 0

    it is concluded that::
        k1=
5
4
        k2=3
    
    There are 2 solution(s).
