What two numbers multiply to -990 and add up to 193?

Here we answer the question: "What two numbers multiply to -990 and add up to 193?"

The answer to your question is:

-5 and 198

Below we illustrate and prove that -5 and 198 multiply to -990 and add up to 193:

-5 × 198 = -990
-5 + 198 = 193

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

x² + 193x - 990 = 0

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

(x - 5 ) (x + 198)

To summarize, since -5 and 198 multiply to -990 and add up 193, you know that the following is true:

x² + 193x - 990 = (x - 5 ) (x + 198)
