Question

simplifya(b-c)-b(c-a)-c(a-b)​

Answer 1

Answer:

2a(b-c)

Step-by-step explanation:

a(b-c) -b(c-a) -c(a-b)

=> ab - ac - bc +ab - ac + bc

=> ab + ab - ac - ac - bc + bc

=> 2ab - 2ac

=> 2a(b-c)

Answer 2

Answer:

a-(b-c) -b(c-a) -c(a-b)

= a-b+c-b + c -a - c + a - b

= a+a-a-b-b-b +c+c-c

= 2a-a-b-b -b+c+c-c

= a-2b-b+c+c-c

= a-3b+c+c-c

= a-3b+2c-c

=a-3b+c
