The correct answer is

2

Let's expand the left-hand side of the equation (x-2)(x-p):

Using the distributive property (also known as the FOIL method for binomials), we have:

\((x-2)(x-p) = x^2 - px - 2x + 2p\)

Simplify this to:

\(x^2 - (p+2)x + 2p\)

We are given that this is equal to \(x^2 - ax + 6\).

By comparing the coefficients of the corresponding terms, we get two equations:

  • From the coefficient of \(x\): \(-a = -(p+2)\), which simplifies to \(a = p+2\)
  • From the constant term: \(2p = 6\), giving \(p = 3\)

Substitute \(p = 3\) into the equation \(a = p+2\):

\(a = 3 + 2 = 5\)

Now, find \(a - p\):

\(a - p = 5 - 3 = 2\)

Thus, the value of \(a-p\) is \(2\).
