Answer:-
Discriminant (d) = -8
Step - by - step explanation:-
Formula used :-
We know that,
Solution :-
According to the question,
Given equation is
Now ,
Standard equation is
Comparing the equation (1) and (2)
We get,
- a = 2
- b = -4
- c= 3
Hence,
For nature of roots,
We know that,
if,
- d <0 (roots are Imaginary)
- d >0 (roots are real)
because( -8< 0)
Hence, The nature of roots of this given equation is imaginary.
