In other words, we want to identify the expression which is a perfect square trinomial.

This expression can be rewritten as,

This is a perfect square trinomial that can be factored as:

This is the square of a binomial.
The correct answer is D
The coordinates of X would be X'(-4, -5).
The equation would be P(x,y) -> P'(-x, y) so you would make the x-coordinate a negative number and keep the y-coordinate the same.
p3 + 13p2 + 8p + 39
