What two numbers multiply to -771 and add up to 254?

Here we answer the question: "What two numbers multiply to -771 and add up to 254?"

The answer to your question is:

-3 and 257

Below we illustrate and prove that -3 and 257 multiply to -771 and add up to 254:

-3 × 257 = -771
-3 + 257 = 254

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

x² + 254x - 771 = 0

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

(x - 3 ) (x + 257)

To summarize, since -3 and 257 multiply to -771 and add up 254, you know that the following is true:

x² + 254x - 771 = (x - 3 ) (x + 257)
