Final answer:
To rewrite the expression A(x) = (x-3)(x+8) in standard form, we need to expand and simplify the expression. The correct answer is B) A(x) = x² + 5x - 24.
Step-by-step explanation:
To rewrite the expression A(x) = (x-3)(x+8) in standard form, we need to multiply out the terms to expand the expression. This gives us A(x) = x² + 5x - 24. Therefore, the correct answer is B) A(x) = x² + 5x - 24.
