1. What can you tell about the parabola by just looking at the equation in expanded or standard form y=x^2+14x+45
2. What is Y=x^2+14x+45 in factored form?
3. What can you tell about the parabola by just looking at the equation in factored form y=(x-10)(x-2)
1. Opens upward.
2. x^2+14x+45 = 0. 45 = 9*5. 9+5 = 14 = B.
Therefore, (x+9) (x+5) = 0
3. X = 10, and X = 2.
