Because the coefficient of x^2 is -1, we know that a will be -1. Knowing that the coefficient of x is -4, we can calculate that p=2. Thus, we have -1(x+2)^2+q is our equation. This is equal to -x^2-4x-4+q. As the constant term must be 2, we can then see that q is 6.
As such, we have -1(x+2)^2+6=0 as our factorization.
To solve this equation, we can use the quadratic formula. Plugging in values, we have:

which is equal to: (when the fraction is simplified)
It looks like selections A and C are identical. (Neither is equivalent to 9^x.)
If B is supposed to be 3^(2x), it is equivalent to F and D and to the given expression.
Of course, D evaluates to 9^x, so is equivalent.
Choice E evaluates to 3^(x+2), which is not equivalent to 3^(2x).
The applicable choices appear to be
... B. 3^(2x)
... D. (3*3)^x
... F. (3^x)*(3^x)
