Simplifying Rational Expressions

Simplifying Rational Expressions

By Brandon Ngo, Abigail Imerson, Dominic Cefalu, and Isabel Rodriguez

Learning Objective:​

Students will learn how to Simplify Rational Expressions through combining like terms, factoring polynomials, and canceling out common factors.​

​

Warm-up with White Boards​

Take about 2 minutes to solve the warm up on your white board and then raise it in the air when we ask you to.

When we have checked everyone's we will go over the problem.​

Some text here about the topic of discussion

​Warm-Up

​Factoring...

​2) x² + 8x + 15

Activity​

​

You and your group will move together and choose one person from the group to use their computer.

Each person needs to take out their notebook, as this will be your notes as well.​

You and your group will have a certain amount of time to solve the problem and choose the correct answer.

After time is up for each question one of us will show how to solve the problem and get the correct answer.

Your goal is to answer as many questions correctly as possible.​

Reminder​: What we write on the white board is your notes make sure you copy down exactly what we write!
