Polynomial Operation Intro

Combing Like Terms

• You have to combine like terms

• x with x and y with y and numbers with numbers

• Remember your signs

What is the value of 6x + 3 - 8x - 5?

• First combine 6x and -8x

• Since 6 - 8 = -2 then it is -2x

• Then combine 3 and -5

• 3 - 5 = -2 also

• Put the two answers together to get -2x - 2
