What two numbers multiply to 616 and add up to -85?

Here we answer the question: "What two numbers multiply to 616 and add up to -85?"

The answer to your question is:

-77 and -8

Below we illustrate and prove that -77 and -8 multiply to 616 and add up to -85:

-77 × -8 = 616
-77 + -8 = -85

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

x² - 85x + 616 = 0

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

(x - 77 ) (x - 8)

To summarize, since -77 and -8 multiply to 616 and add up -85, you know that the following is true:

x² - 85x + 616 = (x - 77 ) (x - 8)
