hope you got your answer

Answer 2

Step-by-step explanation:

(a-b-c) *2 = a*2+b*2+c*2-2ab+2bc-2ac

(3k+4r-2m)*2 = 9k*2+16*2+4m*2-2(3k)(4r)+2(4r)

(2m)

=9k*2+16r*2+4m*2-24kr+16rm-12km

(a+b-c) *2=a*2+b*2+c*2+2ab-2bc-2ac

(3k+4r-2m)*2 = 9k*2+16r*2+4m*2+2(3k)(4r)-2(4r)(2m)-2(3k)(2m)

=9k*2+16r*2+4m*2+24kr-16rm-12km

Therefore

Answer is

18*k2+32r*2+8m*2
