A trinomial is a perfect square trinomial if it can be written in the form $(ax + b)^2 = a^2x^2 + 2abx + b^2$, where $4x^2$ is a perfect square, and $6$ is a perfect square, but the middle term, $-5x$, does not equal $2ab$ for any real numbers $a$ and $b$ that make the first and last terms perfect squares.
