Is 4x squared plus 20x plus 25 a perfect square trinomial?
Yes because its discriminant is equal to zero
Is 81c squared plus 72c plus 16 a perfect square trinomial?
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
What is X squared minus 4x plus 4?
It's a second degree trinomial expression in x. It's a perfect square, being the square of (x-2).
Is x2 plus 32x plus 64 a perfect-square trinomial.?
The given quadratic expression can not be factored as a perfect square.
Is 25x2 70x plus 49 a perfect square trinomial?
Yes.
Is 4x squared plus 20x plus 25 a perfect square trinomial?
Yes because its discriminant is equal to zero
Is 81c squared plus 72c plus 16 a perfect square trinomial?
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
Is x squared - 5x plus 25 a trinomial square?
No.
What is X squared minus 4x plus 4?
It's a second degree trinomial expression in x. It's a perfect square, being the square of (x-2).

The given quadratic expression can not be factored as a perfect square.
Is 4x2 plus 24x plus 18 a perfect square trinomial?
false!
Is 25x2 70x plus 49 a perfect square trinomial?
Yes.
49x2 - 56x plus 16 is a perfect square trinomial?
True
Is X squared minus 14x plus 49 a perfect square trinomial?
Yes because if x2-14x+49 then it is (x-7)(x-7) when factored
Is this trinomial a trinomial square 49y2 - 35y plus 6?
Factors are (7y - 3)(7y - 2) so it's not a perfect square.
