This math topic focuses on multiplying algebraic expressions that involve bracketed terms with the same variable, specifically addressing the multiplication of middle terms. The problems require expanding products of binomials (e.g., (c + 3)(c - 8)) and choosing the correct expanded form from the given options. The expressions involve basic algebraic operations—multiplication of linear binomials and simplifying to obtain a quadratic expression. Each problem features different variables and constants, giving learners a variety of scenarios to practice these algebraic manipulations.
