Simplifying
Simplify a fraction whose numerator is a binomial containing a square root, by simplifying the radical, factoring the numerator, and then canceling common factors with the denominator.
Step 1 — Simplify the radical. The largest perfect square factor of is : . The fraction becomes:
Step 2 — Factor the common factor from the numerator. Both terms in the numerator share the factor : . Rewrite the denominator as :
Step 3 — Remove the common factor. Cancel the shared factor of :
The simplified result is . When the numerator is a binomial that includes a radical, simplify the radical first, then look for a common numerical factor across all terms in the numerator. Factor it out and cancel with the denominator to reduce the fraction.
