Problem Statement

Two polynomials f(x)f(x) and g(x)g(x) with real coefficients are called similar if there exist nonzero real number a such that f(x)=qg(x)f(x) = q \cdot g(x) for all xRx \in R. I. Show that there exists a polynomial P(x)P(x) of degree 1999 with real coefficients which satisfies the condition: (P(x))24(P(x))^2 - 4 and (P(x))2(x24)(P'(x))^2 \cdot (x^2-4) are similar. II. How many polynomials of degree 1999 are there which have above mentioned property.
