Question

Two vectors are given by A = 3i – 2j and B =-i-4 Calculate A + B​

Answer 1

Answer:

A + B = 2i -6j

Explanation:

A = 3i – 2j

B =-i-4j

therefore ,

A + B = (3-1)i + (-2 -4)j

A + B = 2i -6j

Answer 2

Answer:

2i-6j

Explanation:

given : A=3i - 2j

B= - i- 4j

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

ie (3-1)i + (-2+(-4)) j

=2i + (-6) j

= 2i -6j
