Finding Complex Zeros Of Polynomial Functions. 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. When we graph each function we can see these points.
Since we know that one of the zeros of this polynomial is 3 we know that one of the factors is. 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. The real zeros of a polynomial function may be found by factoring where possible or by finding where the graph touches the x axis.
We can get our solutions by using the quadratic formula.
Degree n determines the number of complex zeros of the function. Finding the zeros of a polynomial function with complex zeros. As we mentioned a moment ago the solutions or zeros of a polynomial are the values of x when the y value equals zero polynomials can have real zeros or complex zeros. Find the zeros of f x 3x 3 9x 2 x 3.
