i) Find the complex square roots of -24-10i by solving for x, y real.
ii) Hence, find the roots of the quadratic in "a+ib" form where a, b are real numbers.
i) I got the answer
ii) This is where I have trouble. The question appears to suggest that I use the result of part i) to solve part ii). I'm not sure how they relate. I was thinking of using the quadratic formula, but perhaps there's a quicker way?
Any assistance would be greatly appreciated!
