What two numbers multiply to -520 and add up to 27?

Here we answer the question: "What two numbers multiply to -520 and add up to 27?"

The answer to your question is:

-13 and 40

Below we illustrate and prove that -13 and 40 multiply to -520 and add up to 27:

-13 × 40 = -520
-13 + 40 = 27

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

x² + 27x - 520 = 0

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

(x - 13 ) (x + 40)

To summarize, since -13 and 40 multiply to -520 and add up 27, you know that the following is true:

x² + 27x - 520 = (x - 13 ) (x + 40)
