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

The answer to your question is:

-7 and 54


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

-7 × 54 = -378
-7 + 54 = 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 - 7 ) (x + 54)

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

x2 + 47x - 378 = (x - 7 ) (x + 54)
