Algebra 2: Section 6.4 Factoring and Solving Polynomial Equations (Day 1)

Review of Factoring Factor out GCF if present
Decide on what type of factoring based on the # of terms 2 Terms: Difference of Squares Difference or Sum of Cubes 3 Terms: Trial and Error Perfect Square Trinomial 4 Terms: Grouping

Two # that multiply to get -21 and add up when foiled to get +11
Factoring Quadratics Two # that multiply to get -21 and add up when foiled to get +11

Perfect Square Trinomial

Sum and Difference of Cubes

Rewrite as sum of cubes (Changed order, standard)
Examples Rewrite as sum of cubes (Changed order, standard)

Factoring by Grouping (used when there are 4 terms)
Factor common factor out of first two terms and factor another common factor out of last two terms (may need to rearrange) Factor common binomial out of each ‘term’

Examples Parentheses should be the same! Difference of two squares

Examples

Difference of two squares
Examples Difference of two squares
