What two numbers multiply to 380 and add up to -381?

Here we answer the question: "What two numbers multiply to 380 and add up to -381?"

The answer to your question is:

-380 and -1

Below we illustrate and prove that -380 and -1 multiply to 380 and add up to -381:

-380 × -1 = 380
-380 + -1 = -381

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

x² - 381x + 380 = 0

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

(x - 380 ) (x - 1)

To summarize, since -380 and -1 multiply to 380 and add up -381, you know that the following is true:

x² - 381x + 380 = (x - 380 ) (x - 1)
