How the number of sign changes of a polynomial helps us determine the number or real zeros

The video tutorial explains the concept of real and imaginary solutions, focusing on positive and negative forms of equations. It guides students through simplifying negative forms and determining the number of real solutions using sign changes. The tutorial also covers analyzing zeros and the degree of polynomials, emphasizing the relationship between the degree and the number of zeros, which can be real or imaginary.
