What two numbers multiply to -720 and add up to -719?

Here we answer the question: "What two numbers multiply to -720 and add up to -719?"

The answer to your question is:

-720 and 1

Below we illustrate and prove that -720 and 1 multiply to -720 and add up to -719:

-720 × 1 = -720
-720 + 1 = -719

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

x² - 719x - 720 = 0

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

(x - 720 ) (x + 1)

To summarize, since -720 and 1 multiply to -720 and add up -719, you know that the following is true:

x² - 719x - 720 = (x - 720 ) (x + 1)
