A trinomial [tri implies three] is the product of non-negative Integer powers of variables or we can say an algebraic expression containing 3 terms in it.

Example:

(a + b) Â² = (a + b) (a + b) = aÂ² + 2ab + bÂ²

The Square of any binomial produces the following three terms:

1.The square of the first term of the binomial: aÂ².

2.Twice the product of the two terms: 2ab.

3.The square of the second term: bÂ².

A perfect square of any number is the product of some integer with itself. Hence Perfect Square Trinomial is the product of two same binomials, example, x2 + 4x + 4 is a product of (x + 2) * (x + 2) i.e. (x + 2)2.
