Answer:
a) The discriminant of the equation = - 44
b)The nature of the roots will be imaginary.
c)
Step-by-step explanation:
Here, the given expression is
or,
Now the discriminant (D) of a quadratic equation
D =
Hence, the discriminant of the equation = - 44
As D< 0, so the roots will be imaginary.
Now,by quadratic formula :
So, here
So, either
or,
