Answer:
option 2. 0
Step-by-step explanation:
The discriminant is the part under the square root in the quadratic formula, b²-4ac. If it is more than 0, the equation has two real solutions. if it is 0, the equation has one real solutions. if it is less than 0, the equation has zero real solutions.
-b√b²-4ac /2a
This is because the square root of a negative number cannot give a real number, it will always give an imaginary number
