What two numbers multiply to -308 and add up to 307?

Here we answer the question: "What two numbers multiply to -308 and add up to 307?"

The answer to your question is:

-1 and 308

Below we illustrate and prove that -1 and 308 multiply to -308 and add up to 307:

-1 × 308 = -308
-1 + 308 = 307

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

x² + 307x - 308 = 0

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

(x - 1 ) (x + 308)

To summarize, since -1 and 308 multiply to -308 and add up 307, you know that the following is true:

x² + 307x - 308 = (x - 1 ) (x + 308)
