##### 1 Answer

The discriminant of an equation tells the nature of the roots of a quadratic equation given that a,b and c are rational numbers.

#### Explanation:

The discriminant of a quadratic equation

The discriminant actually tells you the nature of the roots of a quadratic equation or in other words, the number of x-intercepts, associated with a quadratic equation.

Now we have an equation;

Now compare the above equation with quadratic equation

Hence the discriminant (D) is given by;

Therefore the discriminant of a given equation is 0.

Here the discriminant is equal to 0 i.e.
