List all the possible rational roots. (p/q’s) Use a calculator to help determine which values are the roots and perform synthetic division with those roots. Write the polynomial in factored form and determine the zeros of the function. List the multiplicity of each zero. (You will need to use the quadratic formula.) 2. Let . a.

Ask the students to find all the zeros of the polynomial in example 2. Ask the students what they might do with example 3 (They will likely groan). Example 3: Find all the real zeros of the polynomial function . This example leads well into bypassing the rational zero test and using the calculator to determine which possible rational zeros to test.

Find all real and complex zeros of a polynomial function. Find a polynomial with integer coefficients whose zeros are given. Use the Leading Coefficient Test and the zeros of a polynomial to sketch the graph of a polynomial. Apply techniques for approximating real zeros to solve an application problem. Rational Functions
Rational Zeros Theorem Calculator - eMathHelp
The calculator will find all possible rational roots of the polynomial, using the Rational Zeros Theorem. After this, it will decide which possible roots are actually the roots. This is a more general case of the Integer (Integral) Root Theorem (when leading coefficient is `1` or `-1`). Steps are available.

Then state the Rational Zeros Theorem. Pull everything together then and summarize the steps for finding zeros of a polynomial: 1. Use the Rational Zeros Theorem to list possible rational zeros. 2. Use your graphing calculator to help narrow down the choices. 3. Use synthetic division to find the zeros and list factored formula

Graph the function on your calculator to check your answers. When the zeros are all integers it is easy to use the calculator, but if they are not all integers it is hard to tell if it factors or if the solutions are irrational, (i.e. one of the factors is a quadratic that can’t be reduced further using only integer coefficients)

Find the rational zeros and then the other zeros; that is, solve . Factor into linear factors. Solution: Because the degree of is 4, there are at most 4 distinct zeros. The possibilities for are. Now we need to graph the function on a graphing calculator to see which of these possibilities seem to be zeros. When you divide the function by , you ...
