( a + b ) ( b + c ) ( a + b + c ) is equal to

Options

  1. A0
  2. B-[ a b c ]
  3. C2[ a b c ]
  4. D[ array lll a & b & c ] array .

Correct answer

D. [ array lll a & b & c ] array .

Step-by-step solution

aligned & (a+b) (b+c) (a+b+c) & =(a+b) (b a+0+b c+c a+c b+0) & =(a+b) (b a+c a) & =a(b a)+a(c a)+b(b a)+b (c+a) & =0+0+0+[b c a]=[a b c] aligned
