Answer:
Discriminant = -24, no real roots.
Step-by-step explanation:
The discriminant is what's inside the square root in the quadratic formula.
The quadratic formula is:
and 
a = 1
b = 2
c = 7
The question wants the discriminate, we can just focus on the square root part.
When we plug in the parts we got, it becomes:

Since the inside of the square root is negative, there are no real roots.
Answer:
C
Step-by-step explanation:
Good Luck and I hope you do well :)
Answer: maybe 7.5
Step-by-step explanation: I don't really know the question isn't real clear
<span>1/(4p)(x-h)^2+k=0
</span><span>1/(4p)(x-h)^2 = -k
</span>
<span>k(4p)(x-h)^2+1=0
4kp (x^2 - 2xh + h^2) + 1 = 0
4kp x^2 - 8kph x + 4kph^2+1 = 0
D = (-8kph)^2 - 4(4kp)(4kph^2+1) = 64(kph)^2 - 64(kph)^2 - 16kp
D = -16kp < 0
SO discriminant is always less than 0
