What two numbers multiply to -432 and add up to -39?

Here we answer the question: "What two numbers multiply to -432 and add up to -39?"

The answer to your question is:

-48 and 9

Below we illustrate and prove that -48 and 9 multiply to -432 and add up to -39:

-48 × 9 = -432
-48 + 9 = -39

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

x² - 39x - 432 = 0

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

(x - 48 ) (x + 9)

To summarize, since -48 and 9 multiply to -432 and add up -39, you know that the following is true:

x² - 39x - 432 = (x - 48 ) (x + 9)
