Lesson 3.7 Factoring Perfect Square Trinomials
Learning Objectives: SWBAT
1.
Identify a quadratic expressions as a "perfect square trinomial"
2.
Identify and apply the factoring "pattern" associated with perfect square trinomials
Making a connection:
• In Lesson 3.6 we learned that some quadratics have "patterns" for factoring such as
the difference of two perfect squares.
• This lesson deals with another pattern called a perfect square trinomial
Quick Activity - Simplify (multiply) the following perfect squares
Look at your answers above: Do they follow the following pattern?
These patterns can help you quickly factor trinomials, such as y2 + 16y + 64 and
4x2 – 20xy + 25y2
Be careful and do not confuse the “difference of squares” with the “square of a
difference.”
