(2x-1)² =x(4x-1)+2
4x² - 4x + 1 = 4x² -1x +2
-4x +1 x = 2 -1
- 3x = 1 / -3
x = ⅓
4x² - 4x + 1 = 4x² -1x +2
-4x +1 x = 2 -1
- 3x = 1 / -3
x = ⅓
(2x-1)kwadrat=x(4x-1)+2
(2x)kwadrat - 2*2x*1+1kwadrat = 4xkwadrat -x +2
4xkwadrat - 4x +1 = 4xkwadrat -x +2
4xkwadrat - 4x -4xkwadrat +x = 2-1
-3x = 1|:(-3)
x= -1/3
(2x)kwadrat - 2*2x*1+1kwadrat = 4xkwadrat -x +2
