What two numbers multiply to -847 and add up to 846?

Here we answer the question: "What two numbers multiply to -847 and add up to 846?"

The answer to your question is:

-1 and 847

Below we illustrate and prove that -1 and 847 multiply to -847 and add up to 846:

-1 × 847 = -847
-1 + 847 = 846

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

x² + 846x - 847 = 0

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

(x - 1 ) (x + 847)

To summarize, since -1 and 847 multiply to -847 and add up 846, you know that the following is true:

x² + 846x - 847 = (x - 1 ) (x + 847)
