Notes Over 11.4 Simplifying a Rational Expression A fraction whose numerator and denominator are nonzero polynomials. Simplified rational Expression When the numerator and denominator have no factors in common (other than 1) CANCEL FACTORS NOT TERMS! Simplify the expression if possible.

Notes Over 11.4 Simplifying a Rational Expression A fraction whose numerator and denominator are nonzero polynomials. Simplified rational Expression When the numerator and denominator have no factors in common (other than 1) CANCEL FACTORS NOT TERMS! Simplify the expression if possible. Since you cannot factor the numerator, and the numerator and denominator are not exactly the same - then it is already simplified.
