2 Recall what happens when you multiply the following: (x + 4)(x + 4)(x – 3)2The results are called ____________________________.
3 Factoring a Perfect Square Trinomial OR It has to be exactly in this form to use this rule. When you have a base being squared plus or minus twice the product of the two bases plus another base squared, it factors as the sum (or difference) of the bases being squared.
4 Factor the perfect square trinomial: Example 1Factor the perfect square trinomial:If you can recognize that it fits the form of a perfect square trinomial, you can save yourself some time.*Fits the form of a perfect square trinomial *Factor as the sum of bases squared
5 abDoes the middle term fit the pattern, 2ab?Yes, the factors are (a + b)2 :
6 abDoes the middle term fit the pattern, 2ab?Yes, the factors are (a - b)2 :
7 Example 2Factor the following trinomials:x2 + 5x + 12x2 + 6x + 9
8 Example 3Factor the following trinomials:x2 + 8x + 164x2 + 12x + 9
