(4k^2 - 2k + 2)/(k + 3)
.................4k - 14
.......____________
k + 3)4k^2 - 2k + 2
.........4k^2 + 12k
-----------------------------
...............-14k + 2
...............-14k - 42
-----------------------------
........................44
(4k^2 - 2k + 2)/(k + 3)
= (4k + 14) + 44/(k + 3)
= 2[2k + 7 + 22/(k + 3)]

(4k^2 - 2k + 2)/(k + 3)
= (4k + 14) + 44/(k + 3)
= 2[2k + 7 + 22/(k + 3)]
