What two numbers multiply to -111 and add up to 110?

Here we answer the question: "What two numbers multiply to -111 and add up to 110?"

The answer to your question is:

-1 and 111

Below we illustrate and prove that -1 and 111 multiply to -111 and add up to 110:

-1 × 111 = -111
-1 + 111 = 110

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

x² + 110x - 111 = 0

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

(x - 1 ) (x + 111)

To summarize, since -1 and 111 multiply to -111 and add up 110, you know that the following is true:

x² + 110x - 111 = (x - 1 ) (x + 111)
