(2x+1)²=3(2x+1)求解,

(2x+1)²=3(2x+1)求解,
(2x+1)²=3(2x+1)求解,

(2x+1)²=3(2x+1)求解,
(2 x + 1)² = 3(2 x + 1)
(2 x + 1)² - 3(2 x + 1)= 0
(2 x + 1)(2 x + 1 - 3)= 0
(2 x + 1)(2 x - 2)= 0
2 x + 1 = 0 2 x - 2 = 0
2 x1 = - 1 2 x2 = 2
x1 = - 1 / 2 x2 = 1

(2x+1)^2-3(2x+1)=0
(2x+1)(2x+1-3)=0
(2x+1)(2x-2)=0
所以x=-1/2或1

(2x+1)²=3(2x+1)
防城两边除以(2x+1)得:
2x+1=3
2x=3-1
x=1
