Set 5.3b • pp. 242-43
Work only the problems that fit into the three patterns that we took notes over (see below).
Work problems under the three headings. That is, gather all of the same pattern of problems, and work them at the same time.
1. Binomial Squared (see p. 238)
(a + b)^2
(a - b)^2
2. Binomial Inverse (see p. 239)
(a + b)(a - b)
3. Binomial Cubed (see p. 239)
(a + b)^3
(a - b)^3
