What two numbers multiply to -261 and add up to 260?

Here we answer the question: "What two numbers multiply to -261 and add up to 260?"

The answer to your question is:

-1 and 261

Below we illustrate and prove that -1 and 261 multiply to -261 and add up to 260:

-1 × 261 = -261
-1 + 261 = 260

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

x² + 260x - 261 = 0

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

(x - 1 ) (x + 261)

To summarize, since -1 and 261 multiply to -261 and add up 260, you know that the following is true:

x² + 260x - 261 = (x - 1 ) (x + 261)
