Simplify a rational expression

The video tutorial explains the process of factoring rational expressions. It begins with identifying the greatest common factor (GCF) in the denominator and extracting common factors from the numerator. The instructor demonstrates factoring by inspection, focusing on finding values that multiply and add to specific numbers. The tutorial continues with factoring the denominator and simplifying the expression by canceling out common terms, resulting in a simplified rational expression.
