I'm supposed to convert the quadratic equation into complex polar form to find the roots of a quadratic with complex constants. so b^{2}-4ac = p*cis(phi) and (b^2-4ac)^{1/2}has two roots 1.p^{1/2}cis(1/2 * phi+2pi) and 2. p^{1/2}(phi/2)

so I've subbed everything into the equation but it is not simplifying. What is this equation supposed to be, I can't find it in my text book.

Thanks
