Frequently Asked Questions
How do I identify a rational equation?
Look for equations with fractions where the numerator or denominator (or both) contain a variable.
What is the role of common denominators?
Common denominators allow you to combine or eliminate fractions, simplifying the equation for solving.
Why might solutions be extraneous?
Values causing any denominator to be zero are extraneous and must be excluded from solutions.
