There are several ways in which we could answer this question. My choice is to actually solve the given quadratic equation, x^2 + 4x + 4 = 12.
Note that x^2 + 4x + 4 is a perfect square. Thus,
x^2 + 4x + 4 = 12 is the same as (x+2)^2 = 12, so that
x+2 = plus or minus √3*√4, or plus or minus 2√3.
Thus, the two real, unequal roots are
x = -2 + 2√3 and x = -2 - 2√3. These correspond to answer choices C and E.

The answer is 2/3 because you can divide both top and bottom by 12. What you do to the bottom you do to the top. So divide 24 by 12 and you get 2. Divide 36 by 12 and you get 3. Therefore, the answer is 2/3. Hope this helped!
