Answer:
The correct option 3.
Step-by-step explanation:
The given equation is

The discriminant formula is

The value of discriminant for the given quadratic equation is



Therefore the value of the discriminant is 73.
The number of real solution depends on the value of discriminant.
1. If D=0, then the quadratic equation has one real solution.
2. If D>0, then the quadratic equation has two real solutions.
3. If D<0, then the quadratic equation has not real solutions.
Since the value of discriminant is greater than 0, therefore the equation has two real solutions.
Option 3 is correct.
