What two numbers multiply to -378 and add up to -13?

Here we answer the question: "What two numbers multiply to -378 and add up to -13?"

The answer to your question is:

-27 and 14

Below we illustrate and prove that -27 and 14 multiply to -378 and add up to -13:

-27 × 14 = -378
-27 + 14 = -13

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

x² - 13x - 378 = 0

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

(x - 27 ) (x + 14)

To summarize, since -27 and 14 multiply to -378 and add up -13, you know that the following is true:

x² - 13x - 378 = (x - 27 ) (x + 14)
