Hi guys could you check over what i have done and point me in the right direction with part ii

i had to use polinomial division to find the remainder 3x-1 / 9x^5-4x^4

i got the remainder to be 1x or (x) is this correct?

part ii

show using factor theorem that 2x-1 is a factor of 2x^4-x^3-6x^2+5x-1

and express 2x^4-x^3-6x^2+5x-1 as a linear and cubic factor.

TBH i dont know where to start with this one

any guidance appreciated
