What two numbers multiply to -620 and add up to -11?

Here we answer the question: "What two numbers multiply to -620 and add up to -11?"

The answer to your question is:

-31 and 20

Below we illustrate and prove that -31 and 20 multiply to -620 and add up to -11:

-31 × 20 = -620
-31 + 20 = -11

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

x² - 11x - 620 = 0

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

(x - 31 ) (x + 20)

To summarize, since -31 and 20 multiply to -620 and add up -11, you know that the following is true:

x² - 11x - 620 = (x - 31 ) (x + 20)
