This document discusses squaring binomial expressions. It provides three examples of squaring binomials of the form (x + a), showing that (x + a)2 = x2 + 2a*x + a2. Specifically, it squares (x + 3), (b - 5), and (m - 15) to get x2 + 6x + 9, b2 - 10b + 25, and m2 - 60m + 225 respectively.

1. Squaringbinomials

2. Squaring a binomial + 2(x)(3) + 9 x2 (x +3) = 2  6x = x2 + 6x + 9

3. Squaring a binomial - 2(b)(5) + 25 b2 (b - 5) = 2  10b = b2 - 10b + 25

4. Squaring a binomial - 2(m)(15) + 225 m2 (m - 15) = 2  60m = m2 - 60m + 225
