Could you try this again? After applying #8734 to 4.5.3.alpha0 (and
ignoring the patch rejects), I get
{{{
#!python
sage: var('f6,f5,f4,x')
(f6, f5, f4, x)
sage: e=15*f6*x^2 + 5*f5*x + f4
sage: e.roots(x)
[(-1/30*(sqrt(-12*f4*f6 + 5*f5^2)*sqrt(5) + 5*f5)/f6, 1),
(1/30*(sqrt(-12*f4*f6 + 5*f5^2)*sqrt(5) - 5*f5)/f6, 1)]
}}}
