Answer :
A perfect square trinomial is
(square of one term) + (square of another term) + (double the product of the two terms)
(square of one term) + (square of another term) + (double the product of the two terms)
Let's look at the following trinomial.
X² - 14x + 49
(x - 7) (x - 7)
(x - 7)²
This trinomial would be classified as a perfect square trinomial because it factors as two identical binomials which is (x - 7)². This means that any trinomial that factors as two identical binomials is called a perfect square trinomial.
