To verify which expression is equivalent to \((x−5)(x−3)\) using the Distributive Property (also known as the FOIL method for binomials), we can expand the expression:
\[
(x - 5)(x - 3) = x(x) + x(-3) + (-5)(x) + (-5)(-3)
\]
Calculating each term:
1. \(x \cdot x = x^2\)
2. \(x \cdot (-3) = -3x\)
3. \(-5 \cdot x = -5x\)
4. \(-5 \cdot (-3) = 15\)
Now, combine all the terms:
\[
x^2 - 3x - 5x + 15 = x^2 - 8x + 15
\]
Thus, \((x - 5)(x - 3)\) expands to:
\[
x^2 - 8x + 15
\]
Now, we can analyze the provided response options. The expression that we found, \(x^2 - 8x + 15\), matches with one of the responses given.
Therefore, the equivalent expression is:
\[
\boxed{x^2 - 8x + 15}
\]
