Perfect Square Trinomials Pattern
The Perfect Square Trinomials Pattern is a factoring shortcut that reverses the Binomial Squares Pattern. Instead of starting with a binomial and squaring it, you start with a trinomial and factor it back into the square of a binomial. If and are real numbers:
To determine whether a given trinomial fits this pattern, perform three checks:
- Is the first term a perfect square ?
- Is the last term a perfect square ?
- Is the middle term equal to ?
If all three conditions hold, the trinomial factors directly into the square of a binomial. The sign of the middle term determines which form to use: a positive middle term means the factored form uses addition, , while a negative middle term means it uses subtraction, . Although a perfect square trinomial could also be factored using the general methods for trinomials of the form , recognizing the perfect square structure and applying this pattern is significantly faster.
