Observe how the expressions below are factored and observe the relationships of the term with each other.
a. ² + 16 + 64 = (2+8)²
b. 25/² + 10 + 1 = (5 + 1)²
c. 4²-12r +9= (2r- 3)²

1. What can you say about the first term of the factors and to the first term of the given trinomial?
2. What can you say about the last term of the factors and to the last term of the given trinomial?
3. Compare the middle sign of the trinomial to the middle sign of the factors. What did you observed?
4. How was the polynomial factored?
5. What pattern is seen in the factors of the perfect square trinomials?
