What two numbers multiply to 620 and add up to -621?

Here we answer the question: "What two numbers multiply to 620 and add up to -621?"

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 -621:

-620 × -1 = 620
-620 + -1 = -621

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

x² - 621x + 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 -621, you know that the following is true:

x² - 621x + 620 = (x - 620 ) (x - 1)
