What two numbers multiply to -197 and add up to 196?

Here we answer the question: "What two numbers multiply to -197 and add up to 196?"

The answer to your question is:

-1 and 197

Below we illustrate and prove that -1 and 197 multiply to -197 and add up to 196:

-1 × 197 = -197
-1 + 197 = 196

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

x² + 196x - 197 = 0

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

(x - 1 ) (x + 197)

To summarize, since -1 and 197 multiply to -197 and add up 196, you know that the following is true:

x² + 196x - 197 = (x - 1 ) (x + 197)
