Question

If p(x) = x2 – 1 and q (x) = 5 (x minus 1), which expression is equivalent to (p – q)(x)?

Answer 1

All you need to do p(x)-q(x). So:

(x^{2}-1)-(5)(x-1)

That's it!

Answer 2

Explanation:

P(x) = x² - 1 and Q(x) = 5(x - 1)

(P - Q)(x) = x² - 1 - 5(x - 1)

= x² - 1 - 5x + 5

= x² - 5x + 4
