FAQ
Q: What is the purpose of identifying potential zeros in a polynomial function?
A: The purpose of identifying potential zeros is to narrow down the possibilities of where the real zeros of the function might be located.
Q: How are potential zeros found in a polynomial function using factors of the constant and coefficient?
A: Potential zeros are found by listing factors of the constant term and the leading coefficient, adding plus or minus signs, and using these potential roots in the synthetic division process.
Q: What is synthetic division and how is it used to find real zeros?
A: Synthetic division is a method of polynomial division that is used to test potential zeros of a polynomial function. By performing synthetic division with the potential zeros, one can determine if they are actual roots of the function.
Q: Can synthetic division be used to find complex zeros of a polynomial function?
A: No, synthetic division is specifically used for finding real zeros of a polynomial function. Complex zeros require different methods to be identified.
