What two numbers multiply to -900 and add up to -45?

Here we answer the question: "What two numbers multiply to -900 and add up to -45?"

The answer to your question is:

-60 and 15

Below we illustrate and prove that -60 and 15 multiply to -900 and add up to -45:

-60 × 15 = -900
-60 + 15 = -45

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

x² - 45x - 900 = 0

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

(x - 60 ) (x + 15)

To summarize, since -60 and 15 multiply to -900 and add up -45, you know that the following is true:

x² - 45x - 900 = (x - 60 ) (x + 15)
