Using the polynomial remainder theorem you divide the polynomial by a linear polynomial given as x-r, where r is the value of f(x)

You are given the value of f(x) as 4.

So now you have:

x^4 -2x^3+5x^2 -20x-4 / x-4

Divide  

= x^3 +2x^2 +13x +32 +124/x-4


The remainder is the number above the x-4, which is 124.


f(4) = 124

A tire dealer sells 2 tires for as much as he paid for 3 tires. he paid $240 for a dozen tires. What is the total profit on 12 t
tester [92]
First, find how much he paid by tire.
To do so, divide what he paid by how many tires he bought like this :
240$ / 12 = 20$ per tire

Then, calculate how much he sells each tire.
To do so, start by calculating how much he paid for 3 tires:
20$ x 3 = 60$

This is the price he sells 2 tires for, therefore :
60$ / 2 = 30$
he sells his tires 30$ each.

Finally, you have to calculate the profit he made by selling 12.
We already know how much it cost, so you need to find how much money he gets selling them :
12 tires x 30$ = 360$

To find the profit, take off the amount he paid from the amount he made :
360$ - 240$ = 120$

There you go!
