What two numbers multiply to -110 and add up to 109?

Here we answer the question: "What two numbers multiply to -110 and add up to 109?"

The answer to your question is:

-1 and 110

Below we illustrate and prove that -1 and 110 multiply to -110 and add up to 109:

-1 × 110 = -110
-1 + 110 = 109

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

x² + 109x - 110 = 0

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

(x - 1 ) (x + 110)

To summarize, since -1 and 110 multiply to -110 and add up 109, you know that the following is true:

x² + 109x - 110 = (x - 1 ) (x + 110)
