Question

explain the role of discriminate
(∆-delta)and dicuss its effect on roots of quadratic equation
​

Answer 1

Answer:

The discriminant helps us to find the nature of the roots of a quadratic equation.

If D>0, then the roots are real and distinct

if D=0, then the roots are real and equal

if D<0, then there are no real roots

(Here, 'D' refers to Discriminant)

We can find the discriminant by using the following formula:

b^2 - 4ac
