4(x-1/x)+8(x+1/x)=29
4x - 4/x + 8x + 8/x = 29
12x + 4/x - 29 =0
12x^2 + 4 - 29x = 0
12x^2 - 29x + 4 = 0
x = (29+√29^2 - 4*12*4)/2*12 and (29-√29^2 - 4*12*4)/2*12
= (29+√649)/24 and (29-√649)/24
4x - 4/x + 8x + 8/x = 29
12x + 4/x - 29 =0
12x^2 + 4 - 29x = 0
12x^2 - 29x + 4 = 0
x = (29+√29^2 - 4*12*4)/2*12 and (29-√29^2 - 4*12*4)/2*12
= (29+√649)/24 and (29-√649)/24
