Question

the discriminant of the quadratic equationbx^+ax+c=0 where bis not equal to 0​

Answer 1

Answer:

x=2a-b

Step-by-step explanation:

Correct option is

A

real and equal

The roots of a quadratic function are given by x=

2a

−b±

b

2

−4ac

D=b

2

−4ac is called the discriminant

As D=0

x=

2a

−b

is the only root

Hence, the roots of the equation are real and equal when discriminant is zero.
