Dec 21, 2015 · It is known that the roots of the Chebyshev polynomials of the second kind, denote it by $U_n(x)$, are in the interval $(-1,1)$ and they are simple (of multiplicity one). I have noticed that the roots of $U_n{(x)}+U_{n-1}(x)$ (by looking at the law ranks of $n$) also lies in $(-1,1)$, I also noticed that for $(1-x)U_n{(x)}+U_{n-1}(x)$ the roots lie in $(-2,2)$.

A Chebyshev polynomial of either kind with degree n has n different simple rootsChebyshev roots, in the interval [−1, 1] The roots of the Chebyshev polynomial of the first kind are sometimes called Chebyshev nodes because they are used as nodes in polynomial interpolation.
Chebyshev nodes - Wikipedia
https://en.wikipedia.org/wiki/Chebyshev_nodes
The Chebyshev nodes are important in approximation theory because they form a particularly good set of nodes for polynomial interpolation. Given a function ƒ on the interval and points in that interval, the interpolation polynomial is that unique polynomial of degree at most which has value at each point . The interpolation error at is for some (depending on x) in [−1, 1]. So it is logical to try to minimize

K is a nite union of compact intervals. For Chebyshev polynomials of the rst kind, the procedure makes use of a characterization of polynomial nonnegativity. It can incorporate additional constraints, e.g. that all the roots of the polynomial lie inside of K. For Chebyshev polynomials of the second kind, the procedure exploits the method of moments.
