What two numbers multiply to -625 and add up to -120?

Here we answer the question: "What two numbers multiply to -625 and add up to -120?"

The answer to your question is:

-125 and 5

Below we illustrate and prove that -125 and 5 multiply to -625 and add up to -120:

-125 × 5 = -625
-125 + 5 = -120

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

x² - 120x - 625 = 0

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

(x - 125 ) (x + 5)

To summarize, since -125 and 5 multiply to -625 and add up -120, you know that the following is true:

x² - 120x - 625 = (x - 125 ) (x + 5)
