Important: please use " ^ " to indicate exponentiation:
x^4 - 5x^3 + 7x^2 - 4x + 3
If you want to divide this by x-3, synth. division would be perfect. Use +3 as your divisor:

3 / 1 -5 7 -4 3
3 -6 3 -3
-------------------------------
1 -2 1 -1 0 Since the remainder is zero, we know that 3 is a root and (x-3) is a factor. The quotient we can
write using the coefficients shown: {1, -2, 1, -1}:
x^3 - 2x^2 + x - 1 (answer)
