What two numbers multiply to -258 and add up to 127?

Here we answer the question: "What two numbers multiply to -258 and add up to 127?"

The answer to your question is:

-2 and 129

Below we illustrate and prove that -2 and 129 multiply to -258 and add up to 127:

-2 × 129 = -258
-2 + 129 = 127

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

x² + 127x - 258 = 0

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

(x - 2 ) (x + 129)

To summarize, since -2 and 129 multiply to -258 and add up 127, you know that the following is true:

x² + 127x - 258 = (x - 2 ) (x + 129)
