To verify which expression is equivalent to \((x−5)(x−3)\) using the Distributive Property, we will expand the expression:

\[ (x - 5)(x - 3) = x(x - 3) - 5(x - 3) \]

Expanding this:

\[ = x^2 - 3x - 5x + 15 \]

Now, combine the like terms:

\[ = x^2 - 8x + 15 \]

So, \((x−5)(x−3)\) simplifies to \(x^2 - 8x + 15\).

Now, let's check the provided responses:

  1. \(3x^2 - 4x^2 - 3x - 15\) simplifies to \(-x^2 - 3x - 15\) (not equivalent).
  2. \(x^2 - 2x + 15\) (not equivalent).
  3. \(2x - 2\) (not equivalent).
  4. \(x^2 - 8x + 15\) (equivalent).

Thus, the correct expression is:

\(x^2 - 8x + 15\).
