What two numbers multiply to 380 and add up to -81?

Here we answer the question: "What two numbers multiply to 380 and add up to -81?"

The answer to your question is:

-76 and -5

Below we illustrate and prove that -76 and -5 multiply to 380 and add up to -81:

-76 × -5 = 380
-76 + -5 = -81

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

x² - 81x + 380 = 0

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

(x - 76 ) (x - 5)

To summarize, since -76 and -5 multiply to 380 and add up -81, you know that the following is true:

x² - 81x + 380 = (x - 76 ) (x - 5)
