Factor
5x²-28x+32

• (3x-10)(x+6)

• (x-8)(5x-4)

• (5x-8)(x-4)

• (5x-8)(x+7)

Factor
9x²+9x-10

• (3x-5)(3x+2)

• (3x+5)(3x-2)

• Not Factorable

What are the factors of
25x² - 81?

• (5x - 9)(5x + 9)

• (5x - 9)(5x - 9)

• (5x + 9)(5x + 9)

• Cannot be factored

Factor completely: 2x²+22x+60

• (2x+10)(x+6)

• (x+5)(x+6)

• 2(x+1)(x+30)

• 2(x+5)(x+6)

Solve the quadratic equation by factoring.

3x²+9x-30=0

• x= 2, -5

• x= 5, -2

• x= -5, -2

Is x²-16x+64 a perfect square or no?

• It is a perfect square!

• No, it is not a perfect square.

Since x²-16x+64 is a perfect square, do you have to complete the square to change it to vertex form, or can you go straight to factoring it?

• I have to complete the square first :(

• I can go straight to factoring it!
