[ 1/1 Equation]
    Work: Find the solution of equation (1.5+2x)(1+2x) = 3 .
    Question type: Equation
    Solution:Original question:
     (
3
2
+ 2 x )(1 + 2 x ) = 3
    Remove the bracket on the left of the equation:
     Left side of the equation =
3
2
(1 + 2 x ) + 2 x (1 + 2 x )
                                             =
3
2
× 1 +
3
2
× 2 x + 2 x (1 + 2 x )
                                             =
3
2
+ 3 x + 2 x (1 + 2 x )
                                             =
3
2
+ 3 x + 2 x × 1 + 2 x × 2 x
                                             =
3
2
+ 3 x + 2 x + 4 x x
                                             =
3
2
+ 5 x + 4 x x
    The equation is transformed into :
     
3
2
+ 5 x + 4 x x = 3

    After the equation is converted into a general formula, it is converted into:
    ( 2x + 3 )( 4x - 1 )=0
    From
        2x + 3 = 0
        4x - 1 = 0

    it is concluded that::
        x1=-
3
2
        x2=
1
4
    
    There are 2 solution(s).
