Use the Intermediate Value Theorem and synthetic division to determine whether or not the following polynomials have a real zero between the numbers given.
P(x) = x3 - 3x2 + 2x - 5; Is there a real zero between 2 and 3?

Find \(P(2)\) and \(P(3)\) to start with.

Can you do that? To continue, you have to find if 0 is between \(P(2)\) and \(P(3)\).
