Answer:
Option b which is
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.
