No, the negative proposition is the complete negation of the conditional conclusion, and the negation of the proposition is the conditional negation. The conclusion should be denied, but it will become arbitrary in the case of existence and exist in the case of arbitrary changes.

So the negation of the above question is: any x belongs to a real number, x 2-a.

The negative proposition is that there is no X belonging to the real number X 2-A.
