What two numbers multiply to -900 and add up to -899?

Here we answer the question: "What two numbers multiply to -900 and add up to -899?"

The answer to your question is:

-900 and 1

Below we illustrate and prove that -900 and 1 multiply to -900 and add up to -899:

-900 × 1 = -900
-900 + 1 = -899

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

x² - 899x - 900 = 0

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

(x - 900 ) (x + 1)

To summarize, since -900 and 1 multiply to -900 and add up -899, you know that the following is true:

x² - 899x - 900 = (x - 900 ) (x + 1)
