Find the roots of the quartic polynomials given that they are factorable. 1) 2)

7.1 Ansswers

1) I used GeoGebra to find the real roots of the quartic polynomial. The roots are 2.618, 1.618, 0.382, and -0.618. Since the degree is 4, these are all the possible roots for the polynomial. 2) I used GeoGebra to find the real roots of the quartic polynomial. The real roots are 3.41 and 0.59. I used the complex root tool on GeoGebra to find the complex roots. The complex roots are1+1.73i and 1-1.73i.
