Let f be a continuous function defined on [–2013, 2013] such that f(x) is irrational for each $\mathrm{x}\in [-2013,2013]$ and $\mathrm{f}\left(0\right)=2+\sqrt{3}+\sqrt{5}$ The equation $\mathrm{f}\left(2013\right){\mathrm{x}}^2+2\mathrm{f}\left(0\right)\mathrm{x}+\mathrm{f}\left(2013\right)=0$ has
