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:

-14 and 27

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

-14 × 27 = -378
-14 + 27 = 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 - 14 ) (x + 27)

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

x² + 13x - 378 = (x - 14 ) (x + 27)
