What two numbers multiply to -780 and add up to -191?

Here we answer the question: "What two numbers multiply to -780 and add up to -191?"

The answer to your question is:

-195 and 4

Below we illustrate and prove that -195 and 4 multiply to -780 and add up to -191:

-195 × 4 = -780
-195 + 4 = -191

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

x² - 191x - 780 = 0

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

(x - 195 ) (x + 4)

To summarize, since -195 and 4 multiply to -780 and add up -191, you know that the following is true:

x² - 191x - 780 = (x - 195 ) (x + 4)
