What two numbers multiply to -287 and add up to 286?

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

The answer to your question is:

-1 and 287

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

-1 × 287 = -287
-1 + 287 = 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 - 1 ) (x + 287)

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

x² + 286x - 287 = (x - 1 ) (x + 287)
