Answer? +b？ +c？ +4-(ab+3b+2c)≤0

(a-b/2)？ +3(b-2)？ /4+(c- 1)？ ≤0

a-b/2=b-2=c- 1=0

a= 1，b=2，c= 1

200 a+9 b+c = 200+ 18+ 1 = 2 19

Solution: Multiply both sides of the original inequality by 4 to get 4a? +4b？ +4c？ + 16-4ab- 12 b-8c =(2a-b)？ +3(b-2)？ +4(c- 1)？ ≤0.= = = & gt2a-b=0，b-2=0，c- 1=0，= = = & gta= 1，b=2，c= 1。 = = = & gt200a+9b+c=2 19
