$\frac{ 1 }{ i+j }*(i-j)=\frac{ i-j }{ i+j }*\frac{ i-j }{ i-j }=\frac{ (i-j)^2 }{ i^2-j^2 }$

Thanks again! But for some reason the answer is incorrect, The question says: Express the vector in the form (a, b)

3. ghazi

i thought you are asking to simplify you should have said its vector lol

4. yasras

5. ghazi
