The video tutorial explains the rational roots test, a method to find possible rational roots of a polynomial by examining the factors of the constant term and the leading coefficient. It demonstrates the process with an example polynomial, showing how to list possible rational roots and verify them through substitution. The tutorial also identifies actual roots and discusses how to factor the polynomial using these roots.

What is the purpose of the Rational Roots Test?

• To solve a polynomial equation.

• To factor a polynomial completely.

• To determine if a polynomial has any rational roots.

• To find all roots of a polynomial.

Which of the following is NOT a requirement for using the Rational Roots Test?
