How do you write the complex conjugate of the complex number #2ix - i#? Precalculus Complex Numbers in Trigonometric Form Division of Complex Numbers 1 Answer Eddie Jan 4, 2017 # tilde z = - i (2x - 1)# Explanation: if #z = a + i b# then conjugate #tilde z = a - ib# here # z = i (2x - 1)#, ie #b = 2x - 1# So # tilde z = - i (2x - 1)# Answer link Related questions How do I graphically divide complex numbers?
