**Rational Expressions and Equations**

OK, so a rational expression can be expressed in the form of..

Where

*A*, and

*B*are polynomials and

*B*does NOT equal zero. (if it did then it would be undefined)

Therefore, we have to state restrictions on

*x*or any value that would not be permitted. (Anything that would make the denominator have a value of zero).

We ran out of time before we could finish the notes so this will continue on tomorrow.

Oh and no homework today but we have to do TWO exercises tomorrow.
