Question

When asked to find the zeros of the function r(t) = 5t3 – 8t2 + 7t + 2 which task would you complete first - Rational Root Theorem or Descartes’ Rule of Signs? Use complete sentences to explain your reasoning.

Answer 1

I think Rational Root Theorem comes first ... but I have no idea why???

Answer 2

p/q because it gives you a list of possible solutions

Answer 3

by the way degree 3 means you are looking for 3 zeros
and I mention the Rational Root Theorem above.
