What two numbers multiply to 979 and add up to -100?

Here we answer the question: "What two numbers multiply to 979 and add up to -100?"

The answer to your question is:

-89 and -11

Below we illustrate and prove that -89 and -11 multiply to 979 and add up to -100:

-89 × -11 = 979
-89 + -11 = -100

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

x² - 100x + 979 = 0

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

(x - 89 ) (x - 11)

To summarize, since -89 and -11 multiply to 979 and add up -100, you know that the following is true:

x² - 100x + 979 = (x - 89 ) (x - 11)
