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:

-4 and 129

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

-4 × 129 = -516
-4 + 129 = 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 - 4 ) (x + 129)

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

x² + 125x - 516 = (x - 4 ) (x + 129)
