OHST Exam Prep: FOIL & Rational Expressions Flashcards

OHST Exam Prep Series | Field2Compliance

Welcome to the Field2Compliance OHST Exam Prep Series: FOIL & Rational Expressions Flashcards — your quick, focused algebra review for the Occupational Health and Safety Technologist (OHST) exam.

This fast-paced 5-second flashcard session helps you master key algebra skills tested in OHST, CHST, and ASP math sections — especially when evaluating formulas, data, and measurement-based calculations common in workplace safety.

Each flashcard breaks down the FOIL method, quadratic factoring, and rational expressions into simple, visual steps designed to reinforce memory through active recall and repetition. Whether you’re studying during a break, before an exam, or on the job, this session helps you think like an OHST math problem solver.

This lesson is inspired by the structure and problem-solving focus found in OHST Exam Secrets by Mometrix and the Safety Professional’s Reference & Study Guide by Yates (not affiliated). Together, they highlight how fundamental algebra concepts support environmental and safety compliance roles — from calculating exposures and containment to analyzing hazard models.

You’ll Learn and Practice:

• FOIL Method (First, Outer, Inner, Last): Multiply binomials step by step.
• Expand Expressions: For example, (x + 3)(x + 4) = x² + 7x + 12.
• Factor Quadratics: Recognize patterns like x² + 5x + 6 → (x + 2)(x + 3).
• Simplify Rational Expressions: Cancel common factors correctly.
• Avoid Common Mistakes: Never cancel across addition.

These quick examples build the algebraic reasoning needed for safety engineering, exposure modeling, and compliance calculations, where precision and pattern recognition are critical.

Perfect For:

• OHST, CHST, or ASP exam candidates reviewing math fundamentals.
• Environmental and safety professionals brushing up on problem-solving skills.
• Students needing a short, repeatable study session to boost test readiness.

Each formula and factoring pattern appears on-screen for 5 seconds — just enough time to test yourself before the answer appears. Replay the video for reinforcement and improved recall speed.
