What two numbers multiply to -620 and add up to -619?

Here we answer the question: "What two numbers multiply to -620 and add up to -619?"

The answer to your question is:

-620 and 1

Below we illustrate and prove that -620 and 1 multiply to -620 and add up to -619:

-620 × 1 = -620
-620 + 1 = -619

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

x² - 619x - 620 = 0

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

(x - 620 ) (x + 1)

To summarize, since -620 and 1 multiply to -620 and add up -619, you know that the following is true:

x² - 619x - 620 = (x - 620 ) (x + 1)
