Guide Questions (Answer):
1. By factoring the given expressions. And when the factored form of the expression/s is/are written as the square of a binomial, then it is a perfect square trinomial.
2. Basically, no. I can immediately determine whether the trinomial expression is a perfect square trinomial or not
3. Yes. In perfect square trinomial, two of the terms will be perfect squares. The perfect square trinomial is either of the pattern a2 + 2ab + b2 or a2 - 2ab + b2 . These expressions are obtained by squaring the binomials (a+b) and (a-b) respectively.
4. a. The first term of the perfect square trinomial is the square of the first term of the binomial.
b. The second term is twice the product of the two terms of the binomial.
c. The last term of a perfect square trinomial is always positive because the last term is a perfect square.
