What two numbers multiply to -676 and add up to -39?

Here we answer the question: "What two numbers multiply to -676 and add up to -39?"

The answer to your question is:

-52 and 13

Below we illustrate and prove that -52 and 13 multiply to -676 and add up to -39:

-52 × 13 = -676
-52 + 13 = -39

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

x² - 39x - 676 = 0

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

(x - 52 ) (x + 13)

To summarize, since -52 and 13 multiply to -676 and add up -39, you know that the following is true:

x² - 39x - 676 = (x - 52 ) (x + 13)
