Set up the long division.
Notice the 0's put in as place
holders for missing powers of x.x2 = x4x2.Choose x2 since
x2 · x2 matches x4.x4 + 0x3- 3x2 = x2(x2 + 0x - 3).Subtract x4 + 0x3 - 3x2 from
x4 - 2x3 + 0x2 + 8x - 14.
Result is -2x3 + 3x2 + 8x - 14.-2x = -2x3x2.Choose -2x since
-2x · x2 matches -2x3.-2x3 + 0x2 + 6x = -2x(x2 + 0x - 3).Subtract -2x3 + 0x2 + 6x from
-2x3 + 3x2 + 8x - 14..
Result is 3x2 + 2x - 14.3 = 3x2x2.Choose 3 since
3 · x2 matches 3x2.3x2 + 0x2 - 9 = 3(x2 + 0x - 3).Subtract 3x2 + 0x2 - 9 from
3x2 + 2x - 14..
Result is 2x - 5.
2x - 5 is the remainder.
