What two numbers multiply to -622 and add up to 309?

Here we answer the question: "What two numbers multiply to -622 and add up to 309?"

The answer to your question is:

-2 and 311

Below we illustrate and prove that -2 and 311 multiply to -622 and add up to 309:

-2 × 311 = -622
-2 + 311 = 309

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

x² + 309x - 622 = 0

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

(x - 2 ) (x + 311)

To summarize, since -2 and 311 multiply to -622 and add up 309, you know that the following is true:

x² + 309x - 622 = (x - 2 ) (x + 311)
