What two numbers multiply to -515 and add up to 98?

Here we answer the question: "What two numbers multiply to -515 and add up to 98?"

The answer to your question is:

-5 and 103

Below we illustrate and prove that -5 and 103 multiply to -515 and add up to 98:

-5 × 103 = -515
-5 + 103 = 98

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

x² + 98x - 515 = 0

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

(x - 5 ) (x + 103)

To summarize, since -5 and 103 multiply to -515 and add up 98, you know that the following is true:

x² + 98x - 515 = (x - 5 ) (x + 103)
