What two numbers multiply to -842 and add up to 841?

Here we answer the question: "What two numbers multiply to -842 and add up to 841?"

The answer to your question is:

-1 and 842

Below we illustrate and prove that -1 and 842 multiply to -842 and add up to 841:

-1 × 842 = -842
-1 + 842 = 841

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

x² + 841x - 842 = 0

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

(x - 1 ) (x + 842)

To summarize, since -1 and 842 multiply to -842 and add up 841, you know that the following is true:

x² + 841x - 842 = (x - 1 ) (x + 842)
