A student expands -2(4x - 7) and gets -8x + 14. Another student claims the correct expansion is -8x - 14. Evaluate both claims and decide which student, if any, is correct. Provide reasoning.

The first student is correct: -8x + 14, because multiplying two negatives yields a positive for the constant term

The second student is correct: -8x - 14, because a negative outside flips all signs inside

Both are correct for different interpretations of distribution depending on x's value

Neither is correct; the correct expansion is 8x + 14
