Final answer:
A quadratic equation can have 0, 1, or 2 real solutions depending on the discriminant.
Step-by-step explanation:
A quadratic equation can have either 0, 1, or 2 real solutions. To determine the number of real solutions, we can look at the discriminant of the equation, which is the expression under the square root in the quadratic formula.
If the discriminant is greater than 0, there are two real solutions. If the discriminant is equal to 0, there is one real solution. And if the discriminant is less than 0, there are no real solutions.
So, in this case, we need to find the discriminant of the equation to determine the number of real solutions.SPJ11
