What two numbers multiply to 720 and add up to -98?

Here we answer the question: "What two numbers multiply to 720 and add up to -98?"

The answer to your question is:

-90 and -8

Below we illustrate and prove that -90 and -8 multiply to 720 and add up to -98:

-90 × -8 = 720
-90 + -8 = -98

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

x² - 98x + 720 = 0

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

(x - 90 ) (x - 8)

To summarize, since -90 and -8 multiply to 720 and add up -98, you know that the following is true:

x² - 98x + 720 = (x - 90 ) (x - 8)
