What two numbers multiply to 258 and add up to -131?

Here we answer the question: "What two numbers multiply to 258 and add up to -131?"

The answer to your question is:

-129 and -2

Below we illustrate and prove that -129 and -2 multiply to 258 and add up to -131:

-129 × -2 = 258
-129 + -2 = -131

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

x² - 131x + 258 = 0

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

(x - 129 ) (x - 2)

To summarize, since -129 and -2 multiply to 258 and add up -131, you know that the following is true:

x² - 131x + 258 = (x - 129 ) (x - 2)
