Write x2 − 2x − 3 = 0 in the form (x − a)2 = b, where a and b are integers

a.(x − 4)2 = 3
b.(x − 3)2 = 2
c.(x − 2)2 = 1
d.(x − 1)2 = 4

idk but i found this "the graph of y = f(x-2) is the graph of y = f(x) translated two units rightward.  

so, since the point (9,2) lies on the graph of y = f(x), the point (11,2) lies on the graph of y = f(x-2)."
