What two numbers multiply to 515 and add up to 108?

Here we answer the question: "What two numbers multiply to 515 and add up to 108?"

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 108:

5 × 103 = 515
5 + 103 = 108

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

x² + 108x + 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 108, you know that the following is true:

x² + 108x + 515 = (x + 5 ) (x + 103)
