What are rational expressions

The video introduces rational expressions, emphasizing their importance in the course. It explains that rational expressions are fractions where both the numerator and the denominator are polynomials. The video further defines polynomials as sums of monomials with specific properties, such as no negative exponents or variables in denominators. The general form of polynomials is discussed, followed by examples of different types of polynomials like binomials and trinomials. The video concludes with a brief overview of operations on rational expressions, including simplifying and solving equations.
