What two numbers multiply to 500 and add up to -129?

Here we answer the question: "What two numbers multiply to 500 and add up to -129?"

The answer to your question is:

-125 and -4

Below we illustrate and prove that -125 and -4 multiply to 500 and add up to -129:

-125 × -4 = 500
-125 + -4 = -129

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

x² - 129x + 500 = 0

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

(x - 125 ) (x - 4)

To summarize, since -125 and -4 multiply to 500 and add up -129, you know that the following is true:

x² - 129x + 500 = (x - 125 ) (x - 4)
