1. The problem statement, all variables and given/known data Sketch modulus((z+1)/(2z+3))=1 on the complex plane where z=x+iy 2. Relevant equations 3. The attempt at a solution I know it is a circle but i need help simplifying the equation into the form of a circle. i'm stuck at 0= 3x^2 + 3y^2 + 10x + 8 I usually complete the square on these type of problems but it has a 3x^2. What can i do to get it to the form of a circle?
