WebMethod 1: Find The Square Root Of A Complex Number Using Algebra (FOIL & Solve A System Of Equations) To find the square root of a complex number c + di, we can use a similar method to the one we used earlier to find the square root of i. The square root of a + bi is a complex number, so we’ll call it c + di. By the definition of a square root: WebWe can find complex roots of a quadratic equation by using the quadratic formula: \( x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\) By solving the quadratic formula, we will get negative numbers below the square root when the polynomial has complex roots. We simply have to use the imaginary number (square root of -1) to solve. Related calculators ...
