Let P(x) = 0 be an equation whose roots are all non zero real numbers. State a sufficient condition on the coefficients of p(x) that will ensure that the roots of P(x) = 0 occur in reciprocal pairs. That is, if k is a root of p(x) where k doesn't equal 0 and is a real number, then -/k must also be a root. Prove this for fifth and sixth degree polynomials.

What are your thoughts? What have you tried? How far have you gotten? Where are you stuck?

Please be complete. Thank you! ;)
