What two numbers multiply to -190 and add up to 189?

Here we answer the question: "What two numbers multiply to -190 and add up to 189?"

The answer to your question is:

-1 and 190

Below we illustrate and prove that -1 and 190 multiply to -190 and add up to 189:

-1 × 190 = -190
-1 + 190 = 189

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

x² + 189x - 190 = 0

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

(x - 1 ) (x + 190)

To summarize, since -1 and 190 multiply to -190 and add up 189, you know that the following is true:

x² + 189x - 190 = (x - 1 ) (x + 190)
