Question

Both the roots of a quadratic equation are same then what can you
say about the value of discriminant for the equation?
Your answer​

Answer 1

Answer:

The discriminant can be positive, zero, or negative, and this determines how many solutions there are to the given quadratic equation.

A positive discriminant indicates that the quadratic has two distinct real number solutions.

A discriminant of zero indicates that the quadratic has a repeated real number solution.

A negative discriminant indicates that neither of the solutions are real numbers.

Example

We're given a quadratic equation and asked how many solutions it has:

6x2+10

x−1=0

6x 2

+10x−1=06, x, squared, plus, 10, x, minus, 1, equals, 0

From the equation, we see:

a=6

a=6a, equals, 6

b=10

b=10b, equals, 10

c=−1

c=−1c, equals, minus, 1
