I think this is wrong. Statement I is insufficent too. Try with 4. 16-8+A can be positive even if A=-2,-3...... So the right answer should be E. Am I correct? Is A positive?

1)x^2-2x+A is positive for all x 2) Ax^2+1 is positive for all x

Statement (1) ALONE is sufficient, but Statement (2) ALONE is not sufficient Statement (2) ALONE is sufficient, but Statement (1) ALONE is not sufficient BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient EACH statement ALONE is sufficient Statements (1) and (2) TOGETHER are NOT sufficient Statement (1) by itself is sufficient. . For this expression to be always positive has to be more than 0. has to be more than 1.

Statement (2) by itself is insufficient. is positive for all even if is 0.
