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:

1 and 311

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

1 × 311 = 311
1 + 311 = 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 + 1 ) (x + 311)

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

x² + 312x + 311 = (x + 1 ) (x + 311)
