To find the equivalent expression to \((x - 5)(x - 3)\) using the Distributive Property, we can expand it as follows:
\[
(x - 5)(x - 3) = x(x - 3) - 5(x - 3)
\]
Calculating \(x(x - 3)\):
\[
x^2 - 3x
\]
Calculating \(-5(x - 3)\):
\[
-5x + 15
\]
Now, combine the two results:
\[
x^2 - 3x - 5x + 15
\]
Combine like terms:
\[
x^2 - 8x + 15
\]
Now we compare this result with the given options:
1. \(x^2 - 2x + 15\)
2. \(x^2 - 8x + 15\)
3. \(2x - 2\)
4. \(3x^2 - 4x^2 - 3x - 15\)
The expression we derived, \(x^2 - 8x + 15\), is equivalent to the second option:
**x^2 − 8x + 15**
\[
(x - 5)(x - 3) = x(x - 3) - 5(x - 3)
\]
Calculating \(x(x - 3)\):
\[
x^2 - 3x
\]
Calculating \(-5(x - 3)\):
\[
-5x + 15
\]
Now, combine the two results:
\[
x^2 - 3x - 5x + 15
\]
Combine like terms:
\[
x^2 - 8x + 15
\]
Now we compare this result with the given options:
1. \(x^2 - 2x + 15\)
2. \(x^2 - 8x + 15\)
3. \(2x - 2\)
4. \(3x^2 - 4x^2 - 3x - 15\)
The expression we derived, \(x^2 - 8x + 15\), is equivalent to the second option:
**x^2 − 8x + 15**
