(−6)∙(a+2b−3c−4d)−(−2)∙(−4a−3b+2c+d)

"Please Help"? You are drowning and want a life preserver or a lifeguard? Your house is on fire and I should call 911?

(−6)∙(a+2b−3c−4d)−(−2)∙(−4a−3b+2c+d)
= -6a - 12b + 18c + 24d - (8a + 6b - 4c - 2d)
= -6a - 12b + 18c + 24d - 8a - 6b + 4c + 2d
= .....

-14-18b+22c+26d
