1.What is the nature of th roots of f(x) = x^2 + 4x+16-I think it is two conjugate complex roots because it is -2+-2isquare root 3?

2.Nature of roots of f(x) = X^2 + 2x+1 it would be one double root,correct?
I get confused with doing these sometimes, just wanted to verify this is correct-thanks for checking
