1 How to Find the Square Root of a Complex Number
stanleyrabinowitz.comLet us start with the complex number c = a+bi where a and b are real (b =0)and attempt to find an explicit representation for its square root. Of course, every complex number (other than 0) will have two square roots. If w is one square root, then the other one will be −w.Wewill find the one whose real part is non-negative.

Take the square root of both sides and solve for . 2 ( + 4)2 2= √9 + 4 = ±3 = −7 and −1 To complete the square, the coefficient of 2 must be one. If it is any other number, first divide the entire equation by that number.
