Here we answer the question: "What two numbers multiply to -396 and add up to -129?"

The answer to your question is:

-132 and 3

Below we illustrate and prove that -132 and 3 multiply to -396 and add up to -129:

-132 × 3 = -396
-132 + 3 = -129

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² - 129x - 396 = 0

If so, the solution to factor the quadratic equation above is:

(x - 132 ) (x + 3)

To summarize, since -132 and 3 multiply to -396 and add up -129, you know that the following is true:

x² - 129x - 396 = (x - 132 ) (x + 3)
