Now ask the students to complete example 1 by finding all the possible rational roots and checking to see if they are really roots. Example 1: List all the possible rational roots of the polynomial function . Determine which of the possible rational zeros is actually a zero of the function. Ask the students to complete example 2.

Finding Roots of Higher Order Polynomials: Solving polynomials that have a degree greater than those solved in Math I and Math II is going to require the use of skills that were developed when we solved those quadratics last year. Let’s begin by taking a look at some second degree polynomials and the strategies used to solve them.

The roots function returns the zeros of this polynomial. This function is not bulletproof, however. It, along with any root finder, will have some difficulty when roots are repeated several times. (We will demonstrate this later.) The roots function will return complex values when appropriate: »roots([1 0 1]) ans = 0 + 1.0000i. 0 - 1.0000i

(7) 3 roots, 1 real & rational, 2 imaginary, 1 zero. Review solving polynomials by factoring using the Zero Property. Have the students predict the number of roots of x4 – 16 = 0, solve it by factoring into (x + 2)(x – 2)(x2 + 4) = 0 and applying the Zero Property, then predict the number of zeros and end-behavior of the graph of y = x4 – 16.

The value of k for which the RL crosses the imaginary axis is easily found using the Routh test. The characteristic polynomial is found from 1+kG(s) as. The Routh Array is given by. where one has multiplied the third row by k+1. To ensure that all coefficients in the first column are positive, one requires that .
