What two numbers multiply to -130 and add up to -129?

Here we answer the question: "What two numbers multiply to -130 and add up to -129?"

The answer to your question is:

-130 and 1

Below we illustrate and prove that -130 and 1 multiply to -130 and add up to -129:

-130 × 1 = -130
-130 + 1 = -129

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

x² - 129x - 130 = 0

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

(x - 130 ) (x + 1)

To summarize, since -130 and 1 multiply to -130 and add up -129, you know that the following is true:

x² - 129x - 130 = (x - 130 ) (x + 1)
