Practice Simplifying Rational Expressions in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
Simplifying a rational expression by factoring both the numerator and denominator, then canceling common factors. The domain must exclude values that make any original denominator zero.
Just like simplifying the fraction by canceling the common factor of 2, you can simplify by factoring the top as and canceling the common factor. But remember: you can only cancel FACTORS (things being multiplied), not TERMS (things being added).
