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

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

The answer to your question is:

-129 and -1

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

-129 × -1 = 129
-129 + -1 = -130

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

x² - 130x + 129 = 0

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

(x - 129 ) (x - 1)

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

x² - 130x + 129 = (x - 129 ) (x - 1)
