Question

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

Answer 1

Answer:

For the given expression (p-q)(x)

Option C will be correct

Step-by-step explanation:

Given;

       p(x) = x^2-1      

       q(x)= 5(x-1)

Solution:

=(p-q)(x)

=p(x)-q(x)

putting values of p(x) and q(x)          

=(x^2-1)-(5(x-1))

=x^2-1-5(x-1)

Answer 2

Answer:

Option C is correct.

The expression which is equivalent to (p-q)(x)  is, $x^2 -1 - 5(x-1)$

Step-by-step explanation:

Given: $p(x) = x^2 -1$ and q(x) = 5(x-1)

To find the expression which is equivalent to (p-q)(x):

here p and q both are function assuming;

we can write the expression :

(p-q)(x) = p(x) - q(x) = $x^2 -1 - 5(x-1)$

therefore, the expression which is equivalent to (p-q)(x)  is;   $x^2 -1 - 5(x-1)$
