Here we answer the question: "What two numbers multiply to -287 and add up to -286?"

The answer to your question is:

-287 and 1

Below we illustrate and prove that -287 and 1 multiply to -287 and add up to -286:

-287 × 1 = -287
-287 + 1 = -286

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

x² - 286x - 287 = 0

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

(x - 287 ) (x + 1)

To summarize, since -287 and 1 multiply to -287 and add up -286, you know that the following is true:

x² - 286x - 287 = (x - 287 ) (x + 1)
