Week 15- Adding and Subtracring Rational Expressions with Monomial Denominators

To simplify these equations there are a couple of steps you need to follow which are:

1. Find the CD (common denominator)

2. Add or Subtract

3. Simplify more if needed


Here’s a example to show how to do these questions


Pencil is for style*

Step 1: You write out the equation

Step 2: You find out the CD

Step 3: You need to add and subtract together

Step 4: Finally you check to see if you need to simplify more which in this case you do

Then bang you’ve got your anwser
