What two numbers multiply to -516 and add up to -125?

Here we answer the question: "What two numbers multiply to -516 and add up to -125?"

The answer to your question is:

-129 and 4

Below we illustrate and prove that -129 and 4 multiply to -516 and add up to -125:

-129 × 4 = -516
-129 + 4 = -125

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

x² - 125x - 516 = 0

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

(x - 129 ) (x + 4)

To summarize, since -129 and 4 multiply to -516 and add up -125, you know that the following is true:

x² - 125x - 516 = (x - 129 ) (x + 4)
