It seems like you're asking about a mathematical expression rather than a code snippet. If we treat this as an explanation related to programming-like operations, here's what it could mean in a programming context:

This input represents a quadratic expression that needs to be factored completely: -20z^2 + 44z + 48.

If implemented in code, you'd write a program that:

1. Identifies the coefficients: Extracts the coefficients from the quadratic equation, e.g., a = -20, b = 44, c = 48.
2. Factors the equation completely by determining roots or rewriting it as a product of binomials, e.g., (factorization logic).
3. Outputs the simplified factored form.
