A rational expression with a common factor in numerator and denominator is best described as:
ANot yet simplified
BAlready simplified
CAlways undefined
DAlways negative
Answer & Solution
Correct answer: A. Not yet simplified
1. The definition of simplified sets the test.
2. A rational expression is considered simplified if there are no common factors.
3. That applies to its numerator and denominator.
4. A shared factor means that condition is not met.
5. So the expression is not yet simplified.
