  We construct a class of quadratic irrationals having continued fractions of
period $n\geq2$ with "small" partial quotients for which certain integer
multiples have continued fractions of period $1$, $2$ or $4$ with "large"
partial quotients. We then show that numbers in the period of the new continued
fraction are simple functions of the numbers in the periods of the original
continued fraction. We give generalizations of some of the continued fractions
and show that polynomials arising from the generalizations are related to
Chebyshev and Fibonacci polynomials. We then show that some of these
polynomials have a hyperbolic root distribution.
