Determine the value of a (element) of R if -root3i is to be a zero of a+z^2 = a-11/z^2. the answer is a=5, but the book says nothing about this im lost

Hi Barney,
I hope you mean that $\displaystyle -i\sqrt{3}$ satisfies the equation, $\displaystyle a+z^2=\dfrac{a-11}{z^2}$. So substitute $\displaystyle z=-i\sqrt{3}$ to the equation and find the value of a.
