What two numbers multiply to 711 and add up to -88?

Here we answer the question: "What two numbers multiply to 711 and add up to -88?"

The answer to your question is:

-79 and -9

Below we illustrate and prove that -79 and -9 multiply to 711 and add up to -88:

-79 × -9 = 711
-79 + -9 = -88

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

x² - 88x + 711 = 0

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

(x - 79 ) (x - 9)

To summarize, since -79 and -9 multiply to 711 and add up -88, you know that the following is true:

x² - 88x + 711 = (x - 79 ) (x - 9)
