What two numbers multiply to -624 and add up to 98?

Here we answer the question: "What two numbers multiply to -624 and add up to 98?"

The answer to your question is:

-6 and 104

Below we illustrate and prove that -6 and 104 multiply to -624 and add up to 98:

-6 × 104 = -624
-6 + 104 = 98

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

x² + 98x - 624 = 0

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

(x - 6 ) (x + 104)

To summarize, since -6 and 104 multiply to -624 and add up 98, you know that the following is true:

x² + 98x - 624 = (x - 6 ) (x + 104)
