Determine all of the possible rational zeros of a polynomial

The video tutorial explains how to determine possible rational zeros of a polynomial function. It covers the concept of rational zeros, represented as P/Q, where P is the constant term and Q is the leading coefficient. The tutorial details how to find all possible rational zeros by considering the factors of P and Q, and then simplifying these possibilities. It also discusses the application of these rational zeros in finding actual zeros of the polynomial, using methods like graphing and synthetic division.

What is the formula used to express rational zeros of a polynomial function?

• P * Q

• P - Q

• P / Q

• P + Q

Which of the following is a factor of 6?

• ± 5

• ± 3

• ± 7

• ± 8

What is the next step after listing all possible rational zeros?

• Subtract all zeros

• Add all zeros

• Graph the function

• Multiply all zeros

How can you verify if a potential rational zero is an actual zero?

• By multiplying it with the polynomial

• By subtracting it from the polynomial

• By using synthetic division

• By adding it to the polynomial

If you do not have a graphing calculator, what method can you use to find actual zeros?

• Subtracting all potential zeros

• Multiplying all potential zeros

• Adding all potential zeros

• Synthetic division for each potential zero
