pakek cara bersusun sama stematika yah kak plisss banget jawabkan yah kak

...................5x^4 + 18x^2 + 75
...............___________________
x^2 - 4 / 5x^6 - 2x^4 + 3x^2 + 2
.................5x^6 - 20x^4
.............------------------------------------- -
............................18x^4 + 3x^2
............................18x^4 - 72x^2
............-------------------------------------- -
........................................75x^2 + 2
.......................................75x^2 -300
............---------------------------------------- -
......................................................302


(5x^6 - 2x^4 + 3x^2 + 2)/(x^2 - 4)
= (5x^4 + 18x^2 + 75) sisa 302
