Answer 1

To find which expression is equivalent to (x−5)(x−3) using the Distributive Property (also known as the FOIL method for binomials):

1. Distribute each term in the first binomial by each term in the second: \[ (x - 5)(x - 3) = x \cdot x + x \cdot (-3) + (-5) \cdot x + (-5) \cdot (-3) \] \[ = x^2 - 3x - 5x + 15 \] \[ = x^2 - 8x + 15 \]

Now we can verify which expression is equivalent to \(9x^2 - 25\).

The expression \(9x^2 - 25\) is a difference of squares, which can be factored as: \[ 9x^2 - 25 = (3x)^2 - (5)^2 = (3x - 5)(3x + 5) \]

Now, let's look at the options given:

• \((4.5x + 12.5)(4.5x - 12.5)\) - Incorrect
• \(9x(x - 25)\) - Incorrect
• \((3x + 5)(3x - 5)\) - Correct
• \((3x + 5)^2\) - Incorrect

So the equivalent expressions are:

1. For \((x−5)(x−3)\): \(x^2 - 8x + 15\)
2. For \(9x^2 - 25\): \((3x + 5)(3x - 5)\).
