Solve log equations problem
Input
var('x')
solve((log((x**2 - x), 6) - log((6*x - 10), 6) == 0), x)
Output
[log(x^2 - x) == log(6*x - 10)]
But real roots are 5 and 2. What I doing wrong?

I have no problems with 5:
sage: solve((log((x**2 - x), 6) - log((6*x - 10), 6) == 0), x,to_poly_solve=True)
[x == 2, x == 5]
solve((log((x*2 - x), 6) - log((6x - 10), 6) == 0), x,to_poly_solve=True)
