The phrase "a general formula of" is correct and usable in written English.
It can be used when referring to a broad or overarching equation or principle that applies to a particular context or set of circumstances.
Example: "In mathematics, a general formula of the quadratic equation is ax² + bx + c = 0."
Alternatives: "a general equation for" or "a universal formula for".
