Question

which condition is true for real and equal root? a, b^2 - 4ac >0 b. b^2 - 4ac <0​

Answer 1

Answer:

for real and equàl root : b^2-4ac=0

Answer 2

Answer:

$b^{2} -4ac$=0  (answer not given in the option)

Step-by-step explanation:

For a Quadratic eqn., of the form a$x^{2}$+b$x$+c=0 to have its roots of nature, real and equal, the discriminant value ie., $b^{2} -4ac$=0

Here in the question the option is not given.

So, neither of the 2 options are correct
