let root x/1-x be 'y'
y+1/y = 13/6
y2 + 1 / y = 13/6
6y2 +6 = 13y
6y2 -13y+6
now u need to find the values of y
b2 - 4ac
(13)2 - 4 (6)(6)
169-144= 25
-b+- root b2- 4ac/2a (hope you understood the formula - quadratic equations)
13+-5/12
13+5/12 = 18/12 = 9/6 = 3/2
13-5/12 = 8/12 = 4/6 = 2/3
values of y are 3/2 and 2/3
now root x/1-x = y
so root x/1-x = 3/2
square on both sides
x/1-x = 9/4
4x = 9 -9x (solve this :p)
u will get
x = 9/13
now take root x/1-x = 2/3
square on both sides
x/1-x = 4/9
9x = 4-4x (solve it :p)
u will get
x = 4/13
THE VALUES OF x ARE: 9/13 and 4/13
hope u understood :)
