What two numbers multiply to 780 and add up to -88?

Here we answer the question: "What two numbers multiply to 780 and add up to -88?"

The answer to your question is:

-78 and -10

Below we illustrate and prove that -78 and -10 multiply to 780 and add up to -88:

-78 × -10 = 780
-78 + -10 = -88

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

x² - 88x + 780 = 0

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

(x - 78 ) (x - 10)

To summarize, since -78 and -10 multiply to 780 and add up -88, you know that the following is true:

x² - 88x + 780 = (x - 78 ) (x - 10)
