Algebra I

2. 9. 3 - Multiplying Binomials
9.3 - Multiplying Binomials **Remember there are 3 methods to multiply binomials**
Expand and simplify.
(6ℎ−7)(2ℎ+3)
3𝑥−5 (2𝑥+7)

3. Expand and simplify.
a. (4𝐺+7)(𝐺−6) b. 8 𝐵 𝐵 2 +5

4. Multiplying a Trinomial and Binomial
Expand and simplify. a. (4 𝑥 2 +x−6)(2x−3) b. (6𝑛−8)(2 𝑛 2 +𝑛+7)

5. Expand and simplify.
(8𝑞−4)(6 𝑞 2 +𝑞+1)

6. Applying Multiplication of Polynomials
Find the area of the shaded region.

7. 9.4 – Multiplying Special Cases
For these exercises, you must remember that:
𝑎+𝑏 2 = 𝑎 2 +2𝑎𝑏+ 𝑏 2
𝑎−𝑏 2 = 𝑎 2 −2𝑎𝑏+𝑏^2
𝑎+𝑏 𝑎−𝑏 = 𝑎 2 − 𝑏 2

8. Expand and simplify.
a. 3𝑒− b. 2𝑏+9 2

9. Expand and simplify.
a. 3𝑒−5𝑓 b. (2𝑥+3)(2𝑥−3)

10. Expand and simplify.
a. 5𝑝 b. (2 𝑥 2 −11)(2 𝑥 2 +11)
