What two numbers multiply to -125 and add up to 124?

Here we answer the question: "What two numbers multiply to -125 and add up to 124?"

The answer to your question is:

-1 and 125

Below we illustrate and prove that -1 and 125 multiply to -125 and add up to 124:

-1 × 125 = -125
-1 + 125 = 124

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

x² + 124x - 125 = 0

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

(x - 1 ) (x + 125)

To summarize, since -1 and 125 multiply to -125 and add up 124, you know that the following is true:

x² + 124x - 125 = (x - 1 ) (x + 125)
