What two numbers multiply to -600 and add up to -25?

Here we answer the question: "What two numbers multiply to -600 and add up to -25?"

The answer to your question is:

-40 and 15

Below we illustrate and prove that -40 and 15 multiply to -600 and add up to -25:

-40 × 15 = -600
-40 + 15 = -25

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

x² - 25x - 600 = 0

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

(x - 40 ) (x + 15)

To summarize, since -40 and 15 multiply to -600 and add up -25, you know that the following is true:

x² - 25x - 600 = (x - 40 ) (x + 15)
