Find real and imaginary zeros

WebIn order to determine the positive number of real zeroes, we must count the number of sign changes in the coefficients of the terms of the polynomial. The number of real zeroes can then be any positive difference of that number and a positive multiple of two. For the function. there are four sign changes.
