at 3:25, would the constant term be 6 or -6?

Rational Zero Theorem

  • Understand the Rational Zero Theorem and the special case where the leading coefficient is 1. Use it to list all possible rational roots of a polynomial.

  • Use synthetic substitution to test each possible rational root in your list.

  • After you find the first root, try to factor the quotient to find the remaining roots.
