What two numbers multiply to -940 and add up to 939?

Here we answer the question: "What two numbers multiply to -940 and add up to 939?"

The answer to your question is:

-1 and 940

Below we illustrate and prove that -1 and 940 multiply to -940 and add up to 939:

-1 × 940 = -940
-1 + 940 = 939

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

x² + 939x - 940 = 0

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

(x - 1 ) (x + 940)

To summarize, since -1 and 940 multiply to -940 and add up 939, you know that the following is true:

x² + 939x - 940 = (x - 1 ) (x + 940)
