What two numbers multiply to -771 and add up to 770?

Here we answer the question: "What two numbers multiply to -771 and add up to 770?"

The answer to your question is:

-1 and 771

Below we illustrate and prove that -1 and 771 multiply to -771 and add up to 770:

-1 × 771 = -771
-1 + 771 = 770

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

x² + 770x - 771 = 0

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

(x - 1 ) (x + 771)

To summarize, since -1 and 771 multiply to -771 and add up 770, you know that the following is true:

x² + 770x - 771 = (x - 1 ) (x + 771)
