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:

-2 and 310

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

-2 × 310 = -620
-2 + 310 = 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 - 2 ) (x + 310)

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

x² + 308x - 620 = (x - 2 ) (x + 310)
