What two numbers multiply to -616 and add up to -81?

Here we answer the question: "What two numbers multiply to -616 and add up to -81?"

The answer to your question is:

-88 and 7

Below we illustrate and prove that -88 and 7 multiply to -616 and add up to -81:

-88 × 7 = -616
-88 + 7 = -81

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

x² - 81x - 616 = 0

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

(x - 88 ) (x + 7)

To summarize, since -88 and 7 multiply to -616 and add up -81, you know that the following is true:

x² - 81x - 616 = (x - 88 ) (x + 7)
