tentukan hasil bagi dan caranya D. 2X³+7X²-14X-40 oleh 2X-5

...............x^2 + 6x + 8
.............__________________
2x - 5 / 2x^3 + 7x^2 - 14x - 40
..............2x^3 - 5x^2
...........------------------------------------ -
.........................12x^2 - 14x - 40
.........................12x^2 - 30x
..........-------------------------------------- -
......................................16x - 40
......................................16x - 40
.........--------------------------------------- -
...............................................0


Jadi (2x^3 + 7x^2 - 14x - 40) : (2x - 5)
= x^2 + 6x + 8
