Math Problem Statement
Solution
To use the Rational Zeros Theorem to list all possible zeros for the polynomial , we proceed as follows:
-
Identify the leading coefficient and constant term:
- The leading coefficient (coefficient of the highest degree term) is .
- The constant term is .
-
Possible rational zeros: According to the Rational Zeros Theorem, any possible rational zero is of the form , where:
- is a factor of the constant term (5).
- is a factor of the leading coefficient (2).
-
Factors of the constant term (5):
- The factors of 5 are and .
-
Factors of the leading coefficient (2):
- The factors of 2 are and .
-
List all possible values of :
- Taking each combination of factors of 5 over factors of 2, we get:
Therefore, the possible rational zeros are:
You can enter these values in the answer box as:
1, -1, 1/2, -1/2, 5, -5, 5/2, -5/2

- Why is it useful to list all possible rational zeros even if some may not be actual zeros?
Tip: When listing possible rational zeros, always simplify fractions and remember to include both positive and negative values.
