What two numbers multiply to 311 and add up to -312?

Here we answer the question: "What two numbers multiply to 311 and add up to -312?"

The answer to your question is:

-311 and -1

Below we illustrate and prove that -311 and -1 multiply to 311 and add up to -312:

-311 × -1 = 311
-311 + -1 = -312

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

x² - 312x + 311 = 0

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

(x - 311 ) (x - 1)

To summarize, since -311 and -1 multiply to 311 and add up -312, you know that the following is true:

x² - 312x + 311 = (x - 311 ) (x - 1)
