What two numbers multiply to 819 and add up to -100?

Here we answer the question: "What two numbers multiply to 819 and add up to -100?"

The answer to your question is:

-91 and -9

Below we illustrate and prove that -91 and -9 multiply to 819 and add up to -100:

-91 × -9 = 819
-91 + -9 = -100

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

x² - 100x + 819 = 0

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

(x - 91 ) (x - 9)

To summarize, since -91 and -9 multiply to 819 and add up -100, you know that the following is true:

x² - 100x + 819 = (x - 91 ) (x - 9)
