Answer:
-63
Step-by-step explanation:
To find the discriminant, you just need to apply the square root part of the quadratic formula:
Sqrt (b^2 - 4ac)
Sqrt (9 - 4 x 1 x 18)
Sqrt (-63)
The number inside of the square root would be the discriminant.
A negative discriminant means that the quadratic would result in imaginary solutions.
