The video tutorial covers simplifying rational expressions by factoring, using exponent rules, and eliminating common factors. It explains the product, quotient, power, and reciprocal rules for exponents. The tutorial provides examples to demonstrate different methods of simplification, including handling negative exponents and factoring trinomials. The use of a polynomial root finder is also shown to aid in factoring. The video concludes with a comprehensive example of factoring out common factors and simplifying the expression.
