1 Simplifying Rational Expressions We are trying to get common terms to factor ( cancel ) to = 1. You might have to distribute or FOIL to get started. ALWAYS look to factor 1 st ….

2 Simplifying Rational Expressions You CAN NOT factor terms separated by addition and subtraction. We are trying to get common terms to factor ( cancel ) to = 1. You might have to distribute or FOIL to get started. ALWAYS look to factor 1 st …. REMEMBER !!!

3 Simplifying Rational Expressions We are trying to get common terms to factor ( cancel ) to = 1. You might have to distribute or FOIL to get started. ALWAYS look to factor 1 st …. REMEMBER !!! You CAN NOT factor terms separated by addition and subtraction. ONLY multiplication and ONLY terms that are EXACTLY the same !!!

17 Simplifying Rational Expressions EXAMPLE : Simplify When simplifying rational expressions, sometimes the order of terms will be reversed.

18 Simplifying Rational Expressions EXAMPLE : Simplify When simplifying rational expressions, sometimes the order of terms will be reversed. When the terms are separated by addition, the order really doesnt matter and still allows you to cancel…

19 Simplifying Rational Expressions EXAMPLE : Simplify When simplifying rational expressions, sometimes the order of terms will be reversed. When the terms are separated by addition, the order really doesnt matter and still allows you to cancel… When the terms are separated by subtraction, the order does matter. You can still cancel but now we need to place a negative sign in our answer…
