What two numbers multiply to -612 and add up to -39?

Here we answer the question: "What two numbers multiply to -612 and add up to -39?"

The answer to your question is:

-51 and 12

Below we illustrate and prove that -51 and 12 multiply to -612 and add up to -39:

-51 × 12 = -612
-51 + 12 = -39

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

x² - 39x - 612 = 0

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

(x - 51 ) (x + 12)

To summarize, since -51 and 12 multiply to -612 and add up -39, you know that the following is true:

x² - 39x - 612 = (x - 51 ) (x + 12)
