What two numbers multiply to -402 and add up to -131?

Here we answer the question: "What two numbers multiply to -402 and add up to -131?"

The answer to your question is:

-134 and 3

Below we illustrate and prove that -134 and 3 multiply to -402 and add up to -131:

-134 × 3 = -402
-134 + 3 = -131

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

x² - 131x - 402 = 0

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

(x - 134 ) (x + 3)

To summarize, since -134 and 3 multiply to -402 and add up -131, you know that the following is true:

x² - 131x - 402 = (x - 134 ) (x + 3)
