Question 978396: I'm asked to express f(x) in the form f(x) = (x-k)q(x)+r for a given value of k: f(x)=5x^3+x^2+x-7. I understand how to do synthetic division, what I don't understand is what the form (x-k)q(x)+r for a given value of k is.

Your problem description or question is incomplete because you show no value for k. The best you could do is try to factorize the function f(x). A quick check with a graph through google.com suggests f might have ONE real root at or extremely near +1. The other two roots are complex.
