if p(x) = x2 – 1 and q(x)=5(x-1), which expression is equivalent to (p – q)(x)? a: 5(x – 1) – x2 – 1 b: (5x – 1) – (x2 – 1) c: (
x2 – 1) – 5(x – 1) d: (x2 – 1) – 5x – 1
2 answers:
P(x) = x^2 - 1
q(x) = 5(x - 1)
(p - q)(x) = (x^2 - 1) - 5(x - 1)
Answer:
Option c is true.
(
) .
Step-by-step explanation:
We are given:
and
.
Now we are asked to find the expression of:

We know that the expression (p-q)(x) could also be written as:

Hence, 
Hence option c is true i.e. the expression is:
