The first term 2A is a perfect square.2. The 3rd term 2B is a perfect square.3. The middle terms is double the product of the square roots of the first and third terms.OR If the product/sum method for factoring a trinomial is used and the pair of numbers is the same number, this indicates a perfect square trinomial.Factor the following, if possible. Identify which are perfect square trinomials.1)100202 xx2)1692 xx3)91542 xx4)121222 aa5)412 bb6)2218122 yxyx The following binomial pattern is called the Difference of Squares.
