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:

-9 and 48

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

-9 × 48 = -432
-9 + 48 = 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 - 9 ) (x + 48)

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

x² + 39x - 432 = (x - 9 ) (x + 48)
