Question

If the discriminant of an equation is zero, which of the following is true of the equation?

Answer 1

Answer:

If the discriminant of an equation is zero, then the correct statement amongst given statement is:

      a.    It has one real solution

Step-by-step explanation:

We have three cases of discriminant--

• If the discriminant of the equation is strictly greater than zero then the equation has two real solutions.

• If the discriminant is equal to zero then it has one real solution.

• and if the discriminant is strictly less than zero then the equation has 0 real solutions i.e. both the solutions of the equation are complex.

 

Answer 2

The answer would be A. one real solution
