What two numbers multiply to -191 and add up to 190?

Here we answer the question: "What two numbers multiply to -191 and add up to 190?"

The answer to your question is:

-1 and 191

Below we illustrate and prove that -1 and 191 multiply to -191 and add up to 190:

-1 × 191 = -191
-1 + 191 = 190

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

x² + 190x - 191 = 0

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

(x - 1 ) (x + 191)

To summarize, since -1 and 191 multiply to -191 and add up 190, you know that the following is true:

x² + 190x - 191 = (x - 1 ) (x + 191)
