Introduction
Hello! today we will be learning about Rational Expressions. You might be asking"What is a rational expression?" well have no fear. You are about to dive into everything you will need to know about them! Good luck!
Task
- learn how to solve, simplify, and factor rational expressions.
- learn what steps you need to take
- have adept knowladge of rational expressions and polinomials.
_________________________________________________________
1.) What is a GCF and how do we use it in factoring rational expressions?
2.) what is step one of factoring and simplifying?
3.) what is a reciprocal? Give an example.
4.) What is one of the ways that we can get a common denominator?Give an example.
5.) when do we follow the take out a (-) rule?

Conclusion
Great! Hopfully you found all of the information. The answers are as follows:
1. The GCF is that greatest common factor and we use it when factoing a polynomial.
2. Factor the GCF and the simplify
3. The nuber divided by on. (ex. 2 = 1/2)
4. One of the ways is by multiplying the bottom of the fractions.(ex.1/2 * 1/5 = 5/10 * 2/10)
5. if we have two fractions that are being multiplyed we can ntake out a negative and switch the signs.(ex.a-b/b-a * blah/blah. Take put a negative and chenge the b-a to a-b)
