What two numbers multiply to -920 and add up to 919?

Here we answer the question: "What two numbers multiply to -920 and add up to 919?"

The answer to your question is:

-1 and 920

Below we illustrate and prove that -1 and 920 multiply to -920 and add up to 919:

-1 × 920 = -920
-1 + 920 = 919

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

x² + 919x - 920 = 0

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

(x - 1 ) (x + 920)

To summarize, since -1 and 920 multiply to -920 and add up 919, you know that the following is true:

x² + 919x - 920 = (x - 1 ) (x + 920)
