What two numbers multiply to -338 and add up to -13?

Here we answer the question: "What two numbers multiply to -338 and add up to -13?"

The answer to your question is:

-26 and 13

Below we illustrate and prove that -26 and 13 multiply to -338 and add up to -13:

-26 × 13 = -338
-26 + 13 = -13

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

x² - 13x - 338 = 0

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

(x - 26 ) (x + 13)

To summarize, since -26 and 13 multiply to -338 and add up -13, you know that the following is true:

x² - 13x - 338 = (x - 26 ) (x + 13)
