x²- 1/2x - 1/2=0
Taking lcm
( 2x² - 1x - 1) /2 = 0
Transfering 2 to other side
2x² - x - 1 = 0
2x² -2x + x - 1 = 0
2x (x - 1) +1 (x - 1) = 0
(x - 1) ( 2x + 1) = 0
x = 1 or x = -1/2
Taking lcm
( 2x² - 1x - 1) /2 = 0
Transfering 2 to other side
2x² - x - 1 = 0
2x² -2x + x - 1 = 0
2x (x - 1) +1 (x - 1) = 0
(x - 1) ( 2x + 1) = 0
x = 1 or x = -1/2
