Answer:  The required expression is x^2-5x+4.

Step-by-step explanation:  We are given that

p(x)=x^2-1,\\\\q(x)=5(x-1).

We are to find the expression that is equivalent to (p-q)(x).

We know that for any two functions f(x) and g(x), we have

(f-g)(x)=f(x)-g(x).

Therefore we get

(p-q)(x)\\\\=p(x)-q(x)\\\\=(x^2-1)-(5(x-1))\\\\=x^2-1-5x+5\\\\=x^2-5x+4.

Thus, the required expression is x^2-5x+4.

= x²-1-5x+5
=x²-5x+4
