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:

-310 and 1

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

-310 × 1 = -310
-310 + 1 = -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 - 310 ) (x + 1)

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

x² - 309x - 310 = (x - 310 ) (x + 1)
