Aquadratic equation has exactly one real number solution. which is the value of its discriminant? −1 0 1 2

The correct answer option is 0.

Step-by-step explanation:

We know the quadratic formula that we use to find the roots of a quadratic equation:

The discriminant in this formula is the part underneath the square root symbol i.e. b^2-4ac.

For a quadratic equation to have exactly one real number solution, the discriminant must be zero.

As we can see the + and - sign appearing before the discriminant here so for one real number solution, these plus and minus signs need to be removed which can only happen if we have a value of zero.
