What two numbers multiply to -808 and add up to 198?

Here we answer the question: "What two numbers multiply to -808 and add up to 198?"

The answer to your question is:

-4 and 202

Below we illustrate and prove that -4 and 202 multiply to -808 and add up to 198:

-4 × 202 = -808
-4 + 202 = 198

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

x² + 198x - 808 = 0

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

(x - 4 ) (x + 202)

To summarize, since -4 and 202 multiply to -808 and add up 198, you know that the following is true:

x² + 198x - 808 = (x - 4 ) (x + 202)
