hELP ME PLEASE gUYS

@LXelle  @math&ing001 i DID IT IT GAVE ME f(x) = x4 - 3x3 + 6x2 - 18x + 80

Ok let me check.

lxelle · Answer

IMHO, you should revise first before doing your exercises/assignments.

lxelle · Answer

subtract x from each root, and multiply the whole mess together. since they are suggesting a 4th degree poly, you might want to include the conjugate of that complex number

anonymous · Answer

so Lxelle mi answer is wrong

anonymous · Answer

So that's the answer  f(x) = x4 - 3x3 - 6x2 + 18x - 80
