What two numbers multiply to -635 and add up to 122?

Here we answer the question: "What two numbers multiply to -635 and add up to 122?"

The answer to your question is:

-5 and 127

Below we illustrate and prove that -5 and 127 multiply to -635 and add up to 122:

-5 × 127 = -635
-5 + 127 = 122

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

x² + 122x - 635 = 0

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

(x - 5 ) (x + 127)

To summarize, since -5 and 127 multiply to -635 and add up 122, you know that the following is true:

x² + 122x - 635 = (x - 5 ) (x + 127)
