What two numbers multiply to 518 and add up to -261?

Here we answer the question: "What two numbers multiply to 518 and add up to -261?"

The answer to your question is:

-259 and -2

Below we illustrate and prove that -259 and -2 multiply to 518 and add up to -261:

-259 × -2 = 518
-259 + -2 = -261

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

x² - 261x + 518 = 0

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

(x - 259 ) (x - 2)

To summarize, since -259 and -2 multiply to 518 and add up -261, you know that the following is true:

x² - 261x + 518 = (x - 259 ) (x - 2)
