What two numbers multiply to -378 and add up to -47?

Here we answer the question: "What two numbers multiply to -378 and add up to -47?"

The answer to your question is:

-54 and 7

Below we illustrate and prove that -54 and 7 multiply to -378 and add up to -47:

-54 × 7 = -378
-54 + 7 = -47

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

x² - 47x - 378 = 0

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

(x - 54 ) (x + 7)

To summarize, since -54 and 7 multiply to -378 and add up -47, you know that the following is true:

x² - 47x - 378 = (x - 54 ) (x + 7)
