Final answer:
The correct answer is (x - 2)(x + 3).
Step-by-step explanation:
The given options represent different algebraic expressions or equations. Let's analyze each option:
- A. (x - 2)(x + 3) is a factored form of a quadratic expression, which can be expanded to get x^2 + x - 6.
- B. x - 3 is a simple linear expression.
- C. 15a is a monomial, which represents a single term with a coefficient of 15 and a variable of a.
- D. x² + 6x + 5 is a quadratic expression in standard form.
Based on the given factored form and the options, the correct answer is A. (x - 2)(x + 3).
