What two numbers multiply to 520 and add up to 109?

Here we answer the question: "What two numbers multiply to 520 and add up to 109?"

The answer to your question is:

5 and 104

Below we illustrate and prove that 5 and 104 multiply to 520 and add up to 109:

5 × 104 = 520
5 + 104 = 109

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

x² + 109x + 520 = 0

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

(x + 5 ) (x + 104)

To summarize, since 5 and 104 multiply to 520 and add up 109, you know that the following is true:

x² + 109x + 520 = (x + 5 ) (x + 104)
