We have

so this is indeed a difference of squares. Factorizing would give

making the answer D.
We can further factor the first term here and write

but that's clearly out of the scope of this question.
Answer:
I think its A but im not sure
Step-by-step explanation:
Answer:
The standard form of a quadratic equation is:
, 
Quadratic Formula Derivation:



Completing the Square:


Square Root property:



Y = mx+b (slope intercept form). I imagine the point is (2,2) and m = 0. So the answer is y = 2. A sketch would be a horizontal line on the x-y plane going through (2,2).
