Every complex number $z = x + i y$ has associated with it another complex number that is known as its complex conjugate. the complex conjugate can be found simply by changing the sign of the imaginary part of the
complex number.

For example,

let's consider a complex number $z = 2 + 3 i$ then the complex conjugate of this number will be,

$z = 2 - 3 i$ .
