1. Introduction
This document provides the complete solution key and analytical rationales for the WGU C957
Pre-Assessment: Applied Algebra (FXO1) (PFXO), aligned with the 2026-2027 academic standards. The
pre-assessment is designed as the definitive study guide and grading key for students preparing for the
Objective Assessment (OA). The 40-question exam is distributed across four core domains of applied
algebra: linear equations and systems, polynomials and quadratics, exponents and rational expressions, and
functions with graphing applications. Each solution includes a correct answer designation, a step-by-step
mathematical derivation, and an explicit identification of the common algebraic errors that lead to each
distractor. Cognitive levels are distributed as 30% recall, 50% application, and 20% analysis, with 75% of
questions presented in scenario-based (real-world) contexts reflecting 2026 applied math standards.
2. Answer Key
The following table presents the direct answer key for all 40 questions, organized by section.
