Find the remainder when f(x) is divided by (x - k) f(x) = 7x4 + 12x3 + 6x2 - 5x + 16; k = 3
Do you know the remainder theorem?
Have a look here: http://www.mathsisfun.com/algebra/polynomials-remainder-factor.html This is the theorem you need to use in order to solve this. Let me know if you still have questions after looking at this site.
Thanks man. I appreciate your help.
