Is the numerator and denominator of the simplest fraction required to be in the form of multiplication of various factors, or in the form of polynomials, or both Is the numerator and denominator of the simplest fraction in the form of multiplication of factors or polynomial? Or is it all ok
First of all, the numerator and denominator are reduced into product form, and the simplest form is obtained after the same factor is reduced, so it is unnecessary to expand them into polynomials
