Answer:


\text{If p(x) = x2 - 1 and q(x) = 5(x - 1), the expression which is equivalent to}
\text{ (p - q)(x) is (x2 - 1) - 5(x - 1).}

Explanation:

Given:

  • p(x) = 2x2 - 1
  • q(x) = 3(x - 1)

To find:

  • (p - q)(x)

We know:

  • (p - q)(x) = p(x) - q(x)

Substitute

  • (2x^2 - 1) - 3(x - 1)


\text{Therefore, the expression equivalent to (p - q)(x) is (2x2 - 1) - 3(x - 1).}
