What two numbers multiply to -116 and add up to 115?

Here we answer the question: "What two numbers multiply to -116 and add up to 115?"

The answer to your question is:

-1 and 116

Below we illustrate and prove that -1 and 116 multiply to -116 and add up to 115:

-1 × 116 = -116
-1 + 116 = 115

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

x² + 115x - 116 = 0

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

(x - 1 ) (x + 116)

To summarize, since -1 and 116 multiply to -116 and add up 115, you know that the following is true:

x² + 115x - 116 = (x - 1 ) (x + 116)
