(5x⁴ - 3x² + 4) / (x² + 2)
_____5x^2_______________
x^2+2|5x^4 +0x^3 -3x^2 +0x +4
...-.......5x^4...........+10x^2
...............0..+0x^3.-13x^2+0x+4
_____5x^2______-13_______
...-..........................-13x^2.......-26
.....................................0.........+30
SO our answer is 5x^2 -13 + (30/(x^2+2))
5x^2 - 13 remainder 30
ans is 5x^2-7 and remainder18
Explanation
5x^2-7
(x² + 2)|-------------------------
| 5x⁴ +0x^3- 3x² + 4
5x⁴ +0x^3+10x²
