What two numbers multiply to -286 and add up to 285?

Here we answer the question: "What two numbers multiply to -286 and add up to 285?"

The answer to your question is:

-1 and 286

Below we illustrate and prove that -1 and 286 multiply to -286 and add up to 285:

-1 × 286 = -286
-1 + 286 = 285

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

x² + 285x - 286 = 0

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

(x - 1 ) (x + 286)

To summarize, since -1 and 286 multiply to -286 and add up 285, you know that the following is true:

x² + 285x - 286 = (x - 1 ) (x + 286)
