Yes.
The given quadratic expression can not be factored as a perfect square.
Factors are (7y - 3)(7y - 2) so it's not a perfect square.

To determine if (25x^2 + 30xy - 9y^2) is a perfect square trinomial, we check if it can be expressed in the form ((ax + by)^2). The first term, (25x^2), is ((5x)^2) and the last term, (-9y^2), is ((-3y)^2). However, the middle term should equal (2ab), which in this case would be (2(5x)(-3y) = -30xy). Since the middle term matches, (25x^2 + 30xy - 9y^2) is indeed a perfect square trinomial, specifically ((5x - 3y)^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
Yes because 25x2-70x+49 = (5x-7)(5x-7) when factored
