What two numbers multiply to 380 and add up to -39?

Here we answer the question: "What two numbers multiply to 380 and add up to -39?"

The answer to your question is:

-20 and -19

Below we illustrate and prove that -20 and -19 multiply to 380 and add up to -39:

-20 × -19 = 380
-20 + -19 = -39

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

x² - 39x + 380 = 0

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

(x - 20 ) (x - 19)

To summarize, since -20 and -19 multiply to 380 and add up -39, you know that the following is true:

x² - 39x + 380 = (x - 20 ) (x - 19)
