Find the remainder when f(x) is divided by (x - k)
f(x) = 5x4 + 8x3 + 4x2 - 5x + 67; k = 2
I know i have to use the remainder theorm but i just cant get the correct answer... i think its -57?

5x4 +  8x3 + 4x2 - 5x + 67
      0        10      36      80    150
2)    5       18       40     75   R = 217

maybe
