F.5 解方程easy

(3+2/x)(2x-3)=11
(6x-9+4-6/x)=(11)
(6x-5-6/x)x=(11)x
6x^2-5x-6=11x
6x^2-16x-6=0
2(3x^2-8x-3)=0
[2(3x+1)(x-3)]=[0]
[2(3x+1)(x-3)]‧1/2=[0]‧1/2
'' (3x+1)(x-3)=0 ''


(3x+1)=0
3x=-1
x=-1/3

(x-3)=0
x=3

x=-1/3 or 3

( 3+2/x)(2x-3) = 11

(3x+2)(2x-3) = 11x

6x^2 - 16x - 6 = 0

3x^2 - 8x -3 = 0

(3x+1)(x-3) = 0

x = -1/3 or 3
