Florida Algebra 1 EOC cheat sheet

Algebra, functions, equations and data in explicit models

• Factor completely: GCF first, then grouping, special products, or trinomial methods.

• Cancel factors only; terms in a sum cannot be canceled.

• Check radical-equation candidates in the original equation to eliminate extraneous roots.

• The discriminant sign predicts two real, one repeated real, or two complex roots.

• Exclude denominator zeros and negative even-root radicands from domains.

• The domain of a composition is constrained by both the inner and outer functions.

• Define variables, units and domains before solving.

• Equivalent inequalities describe the same solution set.
