How should you factor the following expression?

• Perfect Squares:

  Use (x + a ) (x - a )

• Factor when a>1, slip & slide

• No Leading Coefficient:

  Go straight to (x ± a) (x ± b)

• Factor by Grouping

How should you factor the following expression?  
x² - 5x + 6

• Perfect Squares:
  Use (x + a ) (x - a )

• Perfect Cubes:
  Use SOP SMS

• No Leading Coefficient:
  Go straight to (x ± a) (x ± b)

• Multiply 1st & Last;
  Replace middle term;
  Factor by Grouping

How should you factor the following expression?  
9x² - 12x + 4

• Perfect Squares:
  Use (x + a ) (x - a )

• Perfect Cubes:
  Use SOP SMS
