A trinomial that is a perfect square is derived from the formulae (a^2 + 2ab + b^2) or (a^2 - 2ab + b^2). This result is the outcome of squaring a binomial expression. To determine a perfect square trinomial, it's crucial to verify that the first and third terms are perfect squares, and the middle term equates to double the multiplication of their square roots.
