There are simpler, less error-prone and more intuitive ways to find roots than $p,q$-formulas. I suggest that you learn those instead.

comment Trying to derive two dimensional version of Parseval's theorem (for real valued functions)
There is no such thing as the "Dirac function" — the Dirac delta is a distribution (i.e. generalized function, not probability distribution).
