Example of Simplifying a Rational Expression with Opposite Factors
To simplify a rational expression that contains factors that are opposites, first factor the numerator and denominator completely. Then, identify any factors that are opposites and cancel them, which introduces a factor of .
For example, to simplify :
- Factor the numerator and the denominator to get .
- Recognize that the binomial factors and are opposites.
- Cancel the opposite factors, replacing them with .
- Apply the to the remaining expression to obtain the final simplified result: .
