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:

-13 and 49

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

-13 × 49 = -637
-13 + 49 = 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 - 13 ) (x + 49)

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

x² + 36x - 637 = (x - 13 ) (x + 49)
