Use the rational zero theorem to list all possible rational zeros of the function. In this method we have to find where the graph of a function cut or touch the x axis i e the x intercept. Now that we can find rational zeros for a polynomial function we will look at a theorem that discusses the number of complex zeros of a polynomial function.
Is the factor.
The fundamental theorem of algebra tells us that every polynomial function has at least one complex zero. Multiply both sides by 2. The fundamental theorem of algebra tells us that every polynomial function has at least one complex zero. Use synthetic division to evaluate a given possible zero by synthetically dividing the candidate into the polynomial.
