True
No, it isn't. It would be, if that "36" in the middle were "24" instead.
The given quadratic expression can not be factored as a perfect square.
false!
Yes.
True
Factors are (7y - 3)(7y - 2) so it's not a perfect square.
64
Yes. (Y+5)2
Yes; the factored form would be (9c+4)(9c+4) or just (9c+4)2 Since the two factors are the same, the beginning trinomial 81c2+72c+16 is a perfect square trinomial
(x + 3)(x + 3)
81.
yes, (7x - 4)2
Yes (x+3(x+3)
