What two numbers multiply to -310 and add up to 309?

Here we answer the question: "What two numbers multiply to -310 and add up to 309?"

The answer to your question is:

-1 and 310

Below we illustrate and prove that -1 and 310 multiply to -310 and add up to 309:

-1 × 310 = -310
-1 + 310 = 309

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

x² + 309x - 310 = 0

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

(x - 1 ) (x + 310)

To summarize, since -1 and 310 multiply to -310 and add up 309, you know that the following is true:

x² + 309x - 310 = (x - 1 ) (x + 310)
