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:

-1 and 900

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

-1 × 900 = -900
-1 + 900 = 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 - 1 ) (x + 900)

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

x² + 899x - 900 = (x - 1 ) (x + 900)
