What two numbers multiply to 693 and add up to -86?

Here we answer the question: "What two numbers multiply to 693 and add up to -86?"

The answer to your question is:

-77 and -9

Below we illustrate and prove that -77 and -9 multiply to 693 and add up to -86:

-77 × -9 = 693
-77 + -9 = -86

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

x² - 86x + 693 = 0

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

(x - 77 ) (x - 9)

To summarize, since -77 and -9 multiply to 693 and add up -86, you know that the following is true:

x² - 86x + 693 = (x - 77 ) (x - 9)
