Question 234148
The divisor given to you is (x + 4).  We plug that into (x - c).  Then we use the new value for c as the main factor to multiply each coefficient with.

(x - c) = (x - 4)

We will use -4 as the main factor to multiply each coefficient with.


Also, since no x squared term was given in your numerator, we must keep descending order of exponents when doing division of polynomials.

So, the new numerator becomes 5x^2 + 0x^2 + 6x + 256

The answer will be in the form

trinomilal - remainder/original divisor

Answer:

5x^2 - 20x + 86 - [88/(x + 4)]
