The quadratic equation is in the form : a x² + b x + c = 0
Then the discriminant is: D = b² - 4 a c.
If the discriminant of a quadratic equation is less than zero, it has 2 complex solutions.
If the discriminant of a quadratic equation is equal to zero, it has 1 real solution.
Finally, if the discriminant of a quadratic equation is greater than zero, it has 2 real solutions.
Answer:
C ) It has 2 real solutions.
