What two numbers multiply to -845 and add up to 844?

Here we answer the question: "What two numbers multiply to -845 and add up to 844?"

The answer to your question is:

-1 and 845

Below we illustrate and prove that -1 and 845 multiply to -845 and add up to 844:

-1 × 845 = -845
-1 + 845 = 844

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

x² + 844x - 845 = 0

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

(x - 1 ) (x + 845)

To summarize, since -1 and 845 multiply to -845 and add up 844, you know that the following is true:

x² + 844x - 845 = (x - 1 ) (x + 845)
