Use Descartes Rule of Signs to determine all possible

Last updated: 7/17/2022

Use Descartes Rule of Signs to determine all possible combinations of real and imaginary zeros for the polynomial f(x) = x¹ x³ + 8x - 8. Then find all the real and imaginary zeros of the polynomial given that (x-1) is a factor of the polynomial. All work must be shown for credit.
