What two numbers multiply to 310 and add up to -311?

Here we answer the question: "What two numbers multiply to 310 and add up to -311?"

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 -311:

-310 × -1 = 310
-310 + -1 = -311

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

x² - 311x + 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 -311, you know that the following is true:

x² - 311x + 310 = (x - 310 ) (x - 1)
