Solve $u^2 - u - 25 = 0$, you get $u=\frac{1 \pm \sqrt{101}}{2}$. Now solve ${4 \choose x} = \frac{1 \pm \sqrt{101}}{2}$. In terms of integers this has no solutions. If you use an interpolation of the binomial coefficient, then you may have some solutions. The usual such interpolation comes from replacing each instance of $x!$ in the formula with $\Gamma(x+1)$.
