( [ a +2 b - c , a - b , a - b - c ]= )

Options

  1. A( [ a , b , c ] )
  2. B( 3[ a , b , c ] )
  3. C( 00 )
  4. D( 2[ a , b , c ] )

Correct answer

B. ( 3[ a , b , c ] )

Step-by-step solution

(B) ( ( a +2 b - c ) a - b a - b - c ) ( =( a +2 b - c ) - a b - a c - b a + b c ) ( =[ a b c ]-2[ b a c ] ) ( =[ a b c ]+2[ a b c ] ) ( =3[ a b c ] )
