College Algebra - 50% Get This Wrong — What Is x² When x = −1

In this video, we evaluate a deceptively simple algebra expression: x² When x = −1 Many students (and adults) answer this incorrectly because they rush or forget how negative numbers interact with exponents. This mistake shows up constantly on homework, quizzes, standardized tests, and placement exams. We break the problem down step by step, explain why the correct answer works, and clarify the difference between negative numbers and negative signs — a foundational concept that affects algebra, geometry, and beyond. This is a perfect example of why slowing down and understanding the rules matters more than memorizing tricks.
