What two numbers multiply to -900 and add up to -25?

Here we answer the question: "What two numbers multiply to -900 and add up to -25?"

The answer to your question is:

-45 and 20

Below we illustrate and prove that -45 and 20 multiply to -900 and add up to -25:

-45 × 20 = -900
-45 + 20 = -25

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

x² - 25x - 900 = 0

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

(x - 45 ) (x + 20)

To summarize, since -45 and 20 multiply to -900 and add up -25, you know that the following is true:

x² - 25x - 900 = (x - 45 ) (x + 20)
