Question

by division algorithm find whether or not $x^2 + 5x + 4$ is a factor of $x^4 5x^3+3x^2 -x+4$.

Answer 1

Answer:

Step-by-step explanation:

x^2+5x+4)x^4+5x^3+3x^2-x+4(x^2-1

               x^4+5x^3+4x^2

----------------------------------------------

                     -x^2-x+4

                      -x^2-5x-4

---------------------------------------------

                   4x+8

x^2+5x+4 is not a factor of the given dividend
