What two numbers multiply to -220 and add up to 39?

Here we answer the question: "What two numbers multiply to -220 and add up to 39?"

The answer to your question is:

-5 and 44

Below we illustrate and prove that -5 and 44 multiply to -220 and add up to 39:

-5 × 44 = -220
-5 + 44 = 39

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

x² + 39x - 220 = 0

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

(x - 5 ) (x + 44)

To summarize, since -5 and 44 multiply to -220 and add up 39, you know that the following is true:

x² + 39x - 220 = (x - 5 ) (x + 44)
