Answer:
No because the when you distribute it out it would be (x^2 -1) which is not a perfect square trinomial equation. Also it cannot be a perfect square trinomial because one binomial has negative 1 and the other has positive 1 which indicates that it is not a perfect square.
Explanation:
No.
When you distribute the two factors it would become a perfect square binomial because the -x and the x would cancel out leaving only x^2 -1, which is the difference of two squares.
