What two numbers multiply to -378 and add up to 377?

Here we answer the question: "What two numbers multiply to -378 and add up to 377?"

The answer to your question is:

-1 and 378

Below we illustrate and prove that -1 and 378 multiply to -378 and add up to 377:

-1 × 378 = -378
-1 + 378 = 377

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

x² + 377x - 378 = 0

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

(x - 1 ) (x + 378)

To summarize, since -1 and 378 multiply to -378 and add up 377, you know that the following is true:

x² + 377x - 378 = (x - 1 ) (x + 378)
