Factoring to solve a quadratic TURN IN YOUR WORKSHEET FROM TUESDAY Your chapter 9 quiz is next WED (over )

  Understand the zero product property  Learn how to use factoring to solve a quadratic equation Objectives

 Warm-up

  if a*b=0, then either a =0 or b =0. 1) Solve this equation (x + 5)(2x – 7) = 0 Zero-product Property

 2) Let’s do this 2 ways

 A graph to check…

 3) We will have to factor

 4) What should we do 1 st ?

 You try 5 and 6

 7) Don’t forget old methods…

 8) You try these three

 8b) is this a quadratic??

 8c)

 If there’s time

 HW 9.4 a is in mathxlforschool.com
