Answer:

To do this, you wold need to know the percent error formula.

Percent Error = (Actual value - Expected Value)/Expected Value x 100

Percent Error = (388 - 400)/400 x 100

P.E = (-12)/400 x 100

-0.03 x 100

-3%

(It could possibly positive, if they don't take negative)

Hope this helps!

For this problem, we are going to use the Remainder Theorem. This says that for $x - n$ to be a factor of a polynomial $p(x)$ , then $p(n) = 0$ . Essentially, it says that $x - n$ is a factor if when you substitute $n$ into the polynomial you get a result of 0.

Thus, in our case, when we substitute $x = 2$ into the polynomial, we should get an answer of 0 if $x - 2$ is a factor of the polynomial. Given this information, we can solve for $c$ :
