Factor Quadratic Equations with GCF and Grouping

How do you convert y = 2x² - 5x + 10 to Intercept form?

• Factor

• Complete the Square

• (p+q)/2

• -b/2a

What is the first question you ask yourself when factoring a polynomial? 

• How many terms does it have? 

• Is there a GCF? 

• What strategy should I use? 

• Why do I have to learn this?!?!?!

Factor:   3x²- 6x - 24

• (3x - 8)(x + 3)

• (3x + 4)(x - 6)

• 3(x - 2)(x + 4)

• 3(x + 2)(x - 4)

Factor by GCF

x²-12x

• x²-13x

• 1(x²-12x)

• x(x-12)

Factor: 30x²+15x + 18x + 9

• (5x² - 3)(6x + 1)

• (5x + 9)(2x + 1)

• 3(5x²+3)(2x-1)

• (15x + 9)(2x + 1)

Factor 12x² - 2xy - 4y²

• Take out the GCF

• Factor the rest by any method (x-game, slide & divide and magic square). Final answer should contain the GCF
