Question

what is the value of discriminant will be zero?​

Answer 1

Answer:

the value of D = b^2 -4ac

so if D = 0

IT MEANS THAT THE ROOTS OF THE EQUATION ARE  EQUAL REAL ROOTS  

hope it helps you !!!

Answer 2

Hey mate here's your answer ..

The value of discriminant will be zero only when the quadratic equation have real and equal roots ....

Let us take an example to understand this concept..

Let us take the quadratic equation..2x^2-4x+2..

If we apply discriminant formula here the ans will be..

b^2-4ac=(-4)^2-4(2)(2)

=16-16

=0

Thus...this quad.. equation has real(positive) roots/zeroes and equal in value..

Hope you understood then mark as BRAINLIST..❣
