**Imaginary roots of negative numbers Imaginary and**

z2 = ihas two roots amongst the complex numbers. The quadratic formula (1), is also valid for complex The quadratic formula (1), is also valid for complex coe?cients a,b,c,provided that proper sense is made of the square roots of the complex number b 2 ?4ac.... What is the square root of i? There are two square roots of i how are these answers obtained? An elementary, but not the best, way to obtain this answer is to solve the equation for a and b. If you expand this equation using the rules for complex multiplication, you get . Equating real and imaginary parts gives and 2ab = 1. The equation means . However, if you plug a=-b into the second

The calculator solution will show work to solve a quadratic equation by completing the square to solve the entered equation for real and complex roots. Completing the square when a is not 1 To complete the square when a is greater than 1 or less than 1 but not equal to …

- Let's talk about how to find the roots of a complex number. We'll start with an example. Find the cube roots of 8i. I want to begin this by setting up an equation, z cubed equals 8i. Remember, the cube root of 8i would be a number that when cubed gives you 8i so all the cube roots have to satisfy this equation so I'm looking for solutions to this equation.
