This is the last teaching lesson for this semester, we finish off Chapter 14 for Algebraic Manipulations.

Today we talked about simplifying algebraic fractions, fractions whose numerator and denominator are both polynomials — such expression is called rational expression. We can eliminate the common factors. We talk about how to solve equations with algebraic fractions — such equation is called rational equation. One important thing to remember when solving a rational equation is that any solution cannot make any denominator zero.

We talk about identity equations where it is true for all values for the variable involved.

We will have a review next week, followed by a final exam in two weeks (last day of school).
