Hi , the question and mark scheme answer to part (b) is attached

I don't understand in part (b) why the mark scheme lets z=lambda - (lambda+1) i .

Is it related to the line x+y+1=0 .

Thanks

Hi , I'm stuck after the line u/v= 2lamdba+1

I don't understand how v is multiplied by two on the next line .

Thanks
