What two numbers multiply to -620 and add up to -308?

Here we answer the question: "What two numbers multiply to -620 and add up to -308?"

The answer to your question is:

-310 and 2

Below we illustrate and prove that -310 and 2 multiply to -620 and add up to -308:

-310 × 2 = -620
-310 + 2 = -308

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

x² - 308x - 620 = 0

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

(x - 310 ) (x + 2)

To summarize, since -310 and 2 multiply to -620 and add up -308, you know that the following is true:

x² - 308x - 620 = (x - 310 ) (x + 2)
