Answer 2

Answer: Roots are unequal and real.

Step-by-step explanation:

For finding nature of roots or quadratic equation we will first find its discriminant which is equal to b^2-4ac

where a,b,c are coffecient of x^2,x and x^0 respectively.

(-2)^2-4*(-4)*1

=20

So we can see that it is positive which implies roots are real and unequal.
