What two numbers multiply to -220 and add up to 108?

Here we answer the question: "What two numbers multiply to -220 and add up to 108?"

The answer to your question is:

-2 and 110

Below we illustrate and prove that -2 and 110 multiply to -220 and add up to 108:

-2 × 110 = -220
-2 + 110 = 108

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

x² + 108x - 220 = 0

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

(x - 2 ) (x + 110)

To summarize, since -2 and 110 multiply to -220 and add up 108, you know that the following is true:

x² + 108x - 220 = (x - 2 ) (x + 110)
