This math topic focuses on algebraic function variable substitution, particularly with expressions involving bracketed squared terms. The skill practiced is substituting specific values for variables in algebraic expressions that include terms squared within brackets, and then solving for the numerical results. The questions provide different sets of variable values for which the student needs to evaluate the expressions. Each question offers multiple-choice answers ranging from correct numerical values to potential misconceptions related to sign errors or calculation mistakes. This reinforces understanding of algebraic manipulation and powers while emphasizing attention to detail in solving.
