What two numbers multiply to -621 and add up to -60?

Here we answer the question: "What two numbers multiply to -621 and add up to -60?"

The answer to your question is:

-69 and 9

Below we illustrate and prove that -69 and 9 multiply to -621 and add up to -60:

-69 × 9 = -621
-69 + 9 = -60

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

x² - 60x - 621 = 0

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

(x - 69 ) (x + 9)

To summarize, since -69 and 9 multiply to -621 and add up -60, you know that the following is true:

x² - 60x - 621 = (x - 69 ) (x + 9)
