Distribution/Combine Like Terms

Distribution/Combine Like Terms

Distribution Method

• Let's not forget why we distribute:

• It's to show that you can multiply a number to all the terms inside of the parenthesis

• It's important to put the right signs when doing so.

• In the picture, you'll see that 4 was multiplied to both the x and the 3 inside of the parenthesis

• You can not combine "x" and 12 because they are not like terms

•
