Oct. 4 Class

Today is the first official day of the new unit!  But most of you were more concerned about studying for the unit test tomorrow.  Here anyways is some material for you to start working on reviewing for the next unit.

Unit 3 Daily Plan 

Quadratic Relationship Review

You should work on these as soon as we complete the unit test tomorrow.

Good luck in your studies.

Today was a work/study period for you to review and ask questions about this unit.  Reminder: the test is on Friday!

Here are a couple more practice sheets I handed out today:

Multiplying and dividing rational expressions

Alternate quiz

And here are the solutions!

Learning Goals: Understand how to add subtract and simplify rational expressions.

Today I handed back the test from Unit 1.  If you have any questions about your mark or concerns about the rest of this course, please come see me.

There will be an extra help session today after school and tomorrow after school.

We completed a formative quiz today and here are the solutions:




For the communication questions here is one possible solution:

I would factor the numerator and the denominator.  Then find the restrictions by excluding all values that would make the denominator zero.  Next I would simplify by cancelling any factors that are in both the numerator and denominator.

Up next we will do more review and have the next unit test on Friday.

Homework: P. 132 # 1-16.

Learning Goals: Understand how to add and subtract rational expressions.

We began with a review of how to add fractions, something you should all know from grade 9!

For example, look this:

Easy?  Let's break down all the steps we used to get to the final answer.
  1. Find the lowest common denominator.
  2. Rewrite the numerators.
  3. Add the numerators.
Now we need to apply this to rational expressions.

Example: Add the following, .

The lowest common denominator in this case is 3y.

We rewire the numerators as,.

Now we add the numerators,

And we're done.


Example: Add the following, .

We treat the denominators as factors.  In this case the lowest common denominator is,

LCD: (x+2)(x–3)

Rewrite the numerators, .

Add the numerators, 


And you get the solution: . Restrictions: x ≠ 2, x ≠ 3.


A few things to remember:
  • You should always try to simplify.
  • Don't simplify until the end when everything is in factored form.
  • You cannot simplify when there is still adding and subtracting to be done.
