Question

If p(x)= x^2-1 and q(x)=5(x-1), which expression is equivalent to (p-q)(x)?​

Answer 1

x² - 5x + 4

Explanation:

note that (p - q)(x) = p(x) - q(x), thus

p(x) - q(x)

= x² - 1 - 5(x - 1) ← distribute parenthesis by - 5

= x² - 1 - 5x + 5 ← collect like terms

= x² - 5x + 4

Answer 2

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