Question

x

2

+ 2x + 1 = 0 : Discriminant of the given equation is ________​

Answer 1

Answer:

Correct option is

A

16

3x

2

+2x−1=0

⇒ Here, a=3,b=2,c=−1

⇒ D=b

2

−4ac

=(2)

2

−4(3)(−1)

=4+12

=16

∴ Discriminant =16

Answer 2

Answer:

The answer to this question is 0

Step-by-step explanation:

Discriminant of the quadratic equation $ax^2+bx+c=0$ is $\text{D} = b^2-4ac$

Now according to the given equation a=1 ,b=2 and c=1

Therefore,Discriminant of the given equation is (2² - 4.1.1) = 0
