Answer 2

Answer:

A - B =  i + 4j + 3 k

B - A  = -i - 4j - 3k

Explanation:

A = 2 i + 3j + 4 k

B = i - j + k

A - B = (2 i + 3j + 4 k) - (i - j + k)

=> A - B = 2 i + 3j + 4 k - i + j - k

=>  A - B =  i + 4j + 3 k

B - A  = i - j + k - ( 2i + 3j + 4 k)

=> B - A  = i - j + k - 2i - 3j - 4k

=> B - A  = -i - 4j - 3k
