Question

What is a discriminant of the quadratic equation? What is its formula?

Answer 1

Hey mate...

According to me,
Discriminant is a method to solve quadratic equation. and it is very simple methods than others. It is also shown by the symbol D.

Formula of discriminant.
D =
${b}^{2} - 4ac$

where,
b is a coefficient of y.
a is coefficient of x.
c is constant.

(equation =
$a {x}^{2} + by + c$)I

Answer 2

Answer:

Step-by-step explanation:

Discriminant is a formula for finding that whether the equation will have real roots or not

If value of D (discriminant) is positive ie above 0 so equation will have two real and distinct roots

If D =0 then there will be two real and same roots

And if value of D is negative then the equation will have no real roots

The formula of discriminant is:

D=b^2-4ac

I hope my answer helps you
