What two numbers multiply to -390 and add up to 193?

Here we answer the question: "What two numbers multiply to -390 and add up to 193?"

The answer to your question is:

-2 and 195

Below we illustrate and prove that -2 and 195 multiply to -390 and add up to 193:

-2 × 195 = -390
-2 + 195 = 193

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

x² + 193x - 390 = 0

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

(x - 2 ) (x + 195)

To summarize, since -2 and 195 multiply to -390 and add up 193, you know that the following is true:

x² + 193x - 390 = (x - 2 ) (x + 195)
