Ответ:
Option (b) is correct.
The discriminant for the given quadratic equation
is -7.
Step-by-step explanation:
Given quadratic equation
We have to find the discriminant for the given quadratic equation
.
Consider the quadratic equation
.
The general form form of quadratic equation is
, where a , b, c are the constants.
Discriminant for the general equation given by
Thus, for the given equation a= 1 , b = 1 , c = 2
Substitute , we get,
Solving we get,
Thus, the discriminant for the given quadratic equation
is -7.
Option (b) is correct.
