What two numbers multiply to -396 and add up to 196?

Here we answer the question: "What two numbers multiply to -396 and add up to 196?"

The answer to your question is:

-2 and 198

Below we illustrate and prove that -2 and 198 multiply to -396 and add up to 196:

-2 × 198 = -396
-2 + 198 = 196

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

x² + 196x - 396 = 0

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

(x - 2 ) (x + 198)

To summarize, since -2 and 198 multiply to -396 and add up 196, you know that the following is true:

x² + 196x - 396 = (x - 2 ) (x + 198)
