Question
1. Given the following polynomial: 2x^2 + 7x - 15 = 0 Check all that apply.
The value of the discriminant is 169.
There are 2 real roots.
There are 2 irrational roots.
The graph intersects the y-axis twice.
The parabola is directed upward.
The axis of symmetry is located at: x = -7/4
The vertex is located at: (-7/4, -49/8)
The roots are: {5,3/2}
The graph intersects the y axis at (0, -15).
The graph intersects the x-axis at (-5, 0) and (1.5, 0)
II.
Use the quadratic formula to solve the following: 3x^2 - x + 2 = 0

just to get you started,
2x^2 + 7x - 15 = (2x-3)(x+5)
2x^2 + 7x - 15 = (2x-3)(x+5)
