Question

simplify 3c(-a+2b-c)+2a(b c) then c=2, a=-1 and b=3​

Answer 1

Answer:

-216

Step-by-step explanation:

=3×2(-(-1)+2×3-2)+2×-1(3×2)

=6(1+2×1)-2×6

=6×3×-2×6

=18×-12

=-216

Answer 2

Answer: 18

Step-by-step explanation:

c=2, a=-1, b=3

3c(-a+2b-c)+2a(bc) = 3*2*(-(-1)+2*3-2) + 2*(-1)*(3*2)

= 6*(1+6-2)-2*1*6

=6*5-12

= 30-12

= 18
