Answer:Option b

Step-by-step explanation:We have been given the discriminant 12

We have to choose the equation which will satisfy the given discriminant.

We will consider all the given equation one by one

First we will take option a which is

Discriminant from the equation we will find by the formula

Here, a=-1,b=8 and c=2 on substituting the values we will get

Hence, option a is incorrect.

Now, we will consider option b which is

Here, a=2,b=6 and c=3 on substituting the values we get

Hence, option b is correct

Therefore, option b is the required answer.
