Homework:1. Write out all the perfect squares with factors from 1 to 15. Example: 1*1 = 1, 2*2=4, 15*15=?2. Know all of these perfect squares and be prepared for a quiz on Thursday.
Examples
For every real number a and ba2 + 2ab + b2 = (a+b)(a+b) =(a+b) 2
a2 - 2ab + b2 = (a-b)(a-b)
=(a-b) 2
Perfect Square Trinomial
A. x2 + 8x + 16 = (x+4)(x+4)
= (x+4)2
B. 4n2 – 12n +9 = (2n-3)(2n-3)
= (2n-3)2

Homework:1. Write out all the perfect squares with factors from 1 to 15. Example: 1*1 = 1, 2*2=4, 15*15=?2. Know all of these perfect squares and be prepared for a quiz on Thursday.
Factoring the difference of two squares:
1. The first and last terms are perfect squares How do you recognize a Perfect Square Trinomial?
a2-b2 = (a+b) (a-b)
x2-64 = (x-8)(x+8)
Objective: SWBAT… Factor perfect square trinomials and the difference of two squares
2. The middle term is twice the product of one factor from the first term and one factor from the last term
For al real numbers a and b
