What two numbers multiply to -198 and add up to 97?

Here we answer the question: "What two numbers multiply to -198 and add up to 97?"

The answer to your question is:

-2 and 99

Below we illustrate and prove that -2 and 99 multiply to -198 and add up to 97:

-2 × 99 = -198
-2 + 99 = 97

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

x² + 97x - 198 = 0

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

(x - 2 ) (x + 99)

To summarize, since -2 and 99 multiply to -198 and add up 97, you know that the following is true:

x² + 97x - 198 = (x - 2 ) (x + 99)
