2.Key in the program routines; press †when done.

3.Press WP to start the polynomial root finder.

4.Key in F, the order of the polynomial, and press f

5.At each prompt, key in the coefficient and press f. You're not prompted for the highest–order coefficient — it's assumed to be 1. You must enter 0 for coefficients that are 0. Coefficient A must not be 0.

6.After you enter the coefficients, the first root is calculated. A real root is displayed as %/real value. A complex root is displayed as %/ real part, (Complex roots always occur in pairs of the for u ± i v, and are labeled in the output as %/real part and i =imaginary part, which you'll see in the next step.)

7.Press frepeatedly to see the other roots, or to see i = imaginary part, the imaginary part of a complex root. The order of the polynomial is same as the number of roots you get.

8.For a new polynomial, go to step 3.
