A trinomial square is a perfect square trinomial, which takes the form $a^2 \pm 2ab + b^2$, where it can be factored into $(a \pm b)^2$. The given trinomial $27x^2 - 117x - 90$ does not fit this pattern because its terms do not correspond to the squares and twice the product of two terms that would allow it to be factored into a perfect square.
