For a given complex number $z=a+bi,$ the complex conjugate, written either $z^*$ or $\bar{z},$ is simply $a-bi.$
Of itself this appears to have no real value and hold no interest, but the result of multiplying a complex number by its complex conjugate is a real number. Thus it can be used in the process of dividing complex numbers.
