A quadratic equation has the form

ax^2+bx+c=0

with real coefficients. In

\mathbb{C}

, every quadratic has exactly 2 solutions counting multiplicity (two distinct real, one repeated real with multiplicity 2, or two complex conjugates). For

x^2+4x+4=0

, use the discriminant

b^2-4ac

to predict the solution type and state the solutions counting multiplicity. Which statement is correct?
