Partial fractions with distinct linear factors

Practice partial fractions with distinct linear factors, from choosing the correct decomposition to verifying coefficients by recombination. This precalculus extension set includes proper versus improper rational expressions, nonmonic factors, zero coefficients and original domain restrictions. Single-select and multiselect questions develop conceptual understanding alongside algebraic problem solving. Detailed worked explanations show how clearing denominators creates a polynomial identity and why excluded inputs remain excluded. Review polynomial division, factoring and elementary linear equations before starting.
