IMO the answer is B. Statement 1 does not satisfy the condition.

statement 2:

x2-3x-3x+9=0
x(x-3)-3(x-3)=0
(x-3)(x-3)=0 or sqr(x-3) = 0

ANSWER (B)

how do the statements contradict each other? if one looks at statement 2, the answer is 'yes'.

Statements 1 and 2 do contradict each other here.

Statement 1 gives the explicit answer "NO" and Statement 2 gives the explicit answer "YES".

Even just looking at them in the same form, we get:

1) x^2 - 6x = 21

2) x^2 - 6x = -9

Which means that the two statements are contradictory.

The answer as the question is written would be D, since each statement alone gives a definite answer to the overall question. But because those answers are different, this wouldn't be a valid GMAT question - on the exam if you find that your answers conflict, go back to check your work because you likely did something wrong in calculation.
