What two numbers multiply to -637 and add up to -36?

Here we answer the question: "What two numbers multiply to -637 and add up to -36?"

The answer to your question is:

-49 and 13

Below we illustrate and prove that -49 and 13 multiply to -637 and add up to -36:

-49 × 13 = -637
-49 + 13 = -36

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

x² - 36x - 637 = 0

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

(x - 49 ) (x + 13)

To summarize, since -49 and 13 multiply to -637 and add up -36, you know that the following is true:

x² - 36x - 637 = (x - 49 ) (x + 13)
