Question

A quadratic equation has exactly one real number solution. Which is the value of its discriminant?


−1

0

1

2

Answer 1

Answer: 0

Step-by-step explanation:

We know that if the number of real solutions the quadratic equation depends on the discriminant:-

• If d = 0, then equation will have exactly one real number solution .  
• If d > 0 then equation will have exactly two real number solutions.
• If d < 0  then the quadratic equation will have no real solutions. There will be two complex number solutions.

Therefore, if a quadratic equation has exactly one real number solution.

Then, the value of its discriminant= 0.
