Question

Which expression is equivalent

Answer 1

Answer:
(x^2-1) - 5(x-1)

Explanation:
We are given that:
p(x) = x^2 - 1
q(x) = 5(x-1)

Now, (p-q)(x) means that we will subtract q(x) from p(x) as follows:
p(x) - q(x) = (x^2-1) - 5(x-1)

Comparing this to the choices given, we will find that the correct choice is the third one
