What two numbers multiply to -115 and add up to 114?

Here we answer the question: "What two numbers multiply to -115 and add up to 114?"

The answer to your question is:

-1 and 115

Below we illustrate and prove that -1 and 115 multiply to -115 and add up to 114:

-1 × 115 = -115
-1 + 115 = 114

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

x² + 114x - 115 = 0

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

(x - 1 ) (x + 115)

To summarize, since -1 and 115 multiply to -115 and add up 114, you know that the following is true:

x² + 114x - 115 = (x - 1 ) (x + 115)
