What two numbers multiply to -378 and add up to -57?

Here we answer the question: "What two numbers multiply to -378 and add up to -57?"

The answer to your question is:

-63 and 6

Below we illustrate and prove that -63 and 6 multiply to -378 and add up to -57:

-63 × 6 = -378
-63 + 6 = -57

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

x² - 57x - 378 = 0

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

(x - 63 ) (x + 6)

To summarize, since -63 and 6 multiply to -378 and add up -57, you know that the following is true:

x² - 57x - 378 = (x - 63 ) (x + 6)
