Algebra I (3/4/10) Polynomial Factors: Factoring Trinomials

TN SPI 3102.3.3

Factoring Polynomials : Factoring Trinomials

(page 468)

Student's review multiplying polynomials (Dist. Prop & FOIL) to produce a Trinomial from the product of two Binomials. The process is then reversed and the Trinomials are factored into the product of two Binomials.

The examples grow progressively more difficult and the method of determining the operations present in the two binomial factors is introduced.
