What two numbers multiply to -526 and add up to 261?

Here we answer the question: "What two numbers multiply to -526 and add up to 261?"

The answer to your question is:

-2 and 263

Below we illustrate and prove that -2 and 263 multiply to -526 and add up to 261:

-2 × 263 = -526
-2 + 263 = 261

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

x² + 261x - 526 = 0

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

(x - 2 ) (x + 263)

To summarize, since -2 and 263 multiply to -526 and add up 261, you know that the following is true:

x² + 261x - 526 = (x - 2 ) (x + 263)
