If a trinomial, ax2 + bx + c, has a negative "c" value, what do you know about the signs in its binomial factors.

• The signs are both +

• The signs are both -

• The signs are one + and one -

What is the vertex of this parabola?

• (1, 2)

• (-1, -2)

Solve by factoring: x² - 9x + 20 = 0

• x = -4 and x = -5

• x = 20 and x = -9

• x = 4 and x = 5

• x = -4 and x = 5
