What two numbers multiply to -262 and add up to 129?

Here we answer the question: "What two numbers multiply to -262 and add up to 129?"

The answer to your question is:

-2 and 131

Below we illustrate and prove that -2 and 131 multiply to -262 and add up to 129:

-2 × 131 = -262
-2 + 131 = 129

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

x² + 129x - 262 = 0

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

(x - 2 ) (x + 131)

To summarize, since -2 and 131 multiply to -262 and add up 129, you know that the following is true:

x² + 129x - 262 = (x - 2 ) (x + 131)
