[ 1/1 Equation]
    Work: Find the solution of equation (15-2X)*(8-2X) = 15*8/2 .
    Question type: Equation
    Solution:Original question:
     (152 X )(82 X ) = 15 × 8 ÷ 2
    Remove the bracket on the left of the equation:
     Left side of the equation = 15(82 X )2 X (82 X )
                                             = 15 × 815 × 2 X 2 X (82 X )
                                             = 12030 X 2 X (82 X )
                                             = 12030 X 2 X × 8 + 2 X × 2 X
                                             = 12030 X 16 X + 4 X X
                                             = 12046 X + 4 X X
    The equation is transformed into :
     12046 X + 4 X X = 15 × 8 ÷ 2
     Right side of the equation = 60
    The equation is transformed into :
     12046 X + 4 X X = 60

    After the equation is converted into a general formula, it is converted into:
    ( 2X - 3 )( X - 10 )=0
    From
        2X - 3 = 0
        X - 10 = 0

    it is concluded that::
        X1=
3
2
        X2=10
    
    There are 2 solution(s).
