Menjawab:

# -x ^ 2 + 3x + 2 #

Penjelasan:

# "setiap istilah pada pembilang dibagi dengan" -6x #

# = (6x ^ 3) / (- 6x) - (18x ^ 2) / (- 6x) - (12x) / (- 6x) #

# = (batalkan (6) x ^ ((3-1))) / - batalkan (6) - (batalkan (18) ^ 3x ^ ((2-1))) / (- batalkan (6) ^ 1) -batal (12x) ^ 2 / (- batal (6x) ^ 1) #

# = - x ^ 2 + 3x + 2 #

Menjawab:

#color (crimson) (- x ^ 2 + 3x + 2 #

Penjelasan:

#color (crimson) ((6x ^ 3-18x ^ 2-12x) / (- 6x) #

#color (white) (..) color (white) (….) - x ^ 2 + 3x + 2 #

# -6x | overline (6x ^ 3-18x ^ 2-12x) #

#color (white) (……….) 6x ^ 3 #

#color (white) (…………….) overline (-18x ^ 3) #

#color (white) (…………….) ul (-18x ^ 3) #

#color (white) (……………………..) - 12x #

#color (white) (……………………….) ul (-12x) #

#color (crimson) ((6x ^ 3-18x ^ 2-12x) / (-6x) = -x ^ 2 + 3x + 2 #
