This week in math we learned how to simplify a rational expression and determine the non-permissible values. The expression below is an example of how to do this.
The first step is to determine the non-permissible values which for now are only Y cannot equal 3.
Now that you have flipped the fraction you have to determine the new non-permissible values of the second fraction which are, Y cannot equal 0,-1.
you can now cross out the top of the fraction with the bottom of the fraction. Then you end up with:
