This week in Pre-Calc 11 we learned about a cncept that is very hard for me, called “Rational Expressions. A rational expression is the quoient of two polynomials. This unit requires a lot of factoring, and also a lot of self control. By that I mean, you have to realyy stop yourself from simplifying any further, otherwise your answer will be completely wrong. This unit is especially hard when you are adding and subtracting rational expressions, because you have to find a common denominator with polynomials that have nothing in common. This unit requires a lot of thinking and practicing. The main thing to remember in this unit is that once you’ve done the necessary steps, don’t try to simplify any further. Also if you’re subtracting, always remember to disttibute your negative and change the correct signs to their opposites.

Here are some examples of rational expressions
