8.2 Multiplying Binomials
Objective Multiplying two binomials or a binomial and a trinomial.
Example 1 – Using the Distributive Property What is the simplified form of (x + 4)(2x – 1)?
Example 2 – Using a Table What is the simplified form of (3x + 1)(4x – 2)?
Example 3 – Using FOIL What is the simplified form of (7x – 1)(x – 4)?
Example 5 – Multiplying a Trinomial and a Binomial What is the simplified form of (2x2 – 5x + 4)(x + 3)?
