Ellenochka Земеним $\frac{x^2-x-1}{3x-5} = y$ , тогда $( \frac{x^2-x-1}{3x-5})^2 = y^2$
y² + y - 2 =0
y₁=-2 y₂=1

$\frac{x^2-x-1}{3x-5} = -2$
x²-x-1=-2(3x-5)
x²-x-1=-6x+10
x²+5x-11=0
D=25-4(-11)=69
$x_1= \frac{-5- \sqrt{69} }{2}$ u $x_2= \frac{-5+ \sqrt{69} }{2}$

$\frac{x^2-x-1}{3x-5} = 1\\x^2-x-1=3x-5\\x^2-4x+4=0$
D=16-4·4=0
x₃ = 2
