What is a requirement for a trinomial to be factored as a perfect square?

A perfect square is a binomial squared, like (x+3)^2. You would calculate this by remembering: Square the first, twice the product, square the last. So x^2 (square the first), plus 6x (twice the product), plus 9 (square the last), so we get x^2+6x+9. We can factor this in reverse to see that this is a perfect square. With this simple trick, you can solve for perfect squares.

If you mean: n2+20n+100 then yes it is because (n+10)(n+10) when factored
Is x2-25x 100 a trinomial square?
If you mean: x2-25x+100 then it is (x-5)(x-20) when factored
How do you complete the square to make a binomial a perfect-square trinomial?
The binomial usually has an x2 term and an x term, so we complete the square by adding a constant term. If the coefficient of x2 is not 1, we divide the binomial by that coefficient first (we can multiply the trinomial by it later). Then we divide the coefficient of x by 2 and square that. That is the constant that we need to add to get the perfect square trinomial. Then just multiply that trinomial by the original coefficient of x2.
Is 9x2-36x 16 a perfect square trinomial?
If you mean: 9x2-36x+16 then it is not a perfect square because its discriminant is greater than zero

It can be factored as the SQUARE OF A BINOMIAL
What is a perfect square trinomial and how is it factored?
A trinomial of the form ax2 + bx + c is a perfect square if (and only if) b2-4ac = 0 and, in that case, it is factored into a*(x + b/2a)2
When do you say that a trinomial is a perfect square?
A trinomial is perfect square if it can be factored into the form (a+b)2 So a2 +2ab+b2 would work.

The given quadratic expression can not be factored as a perfect square.
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
