What two numbers multiply to 618 and add up to 311?

Here we answer the question: "What two numbers multiply to 618 and add up to 311?"

The answer to your question is:

2 and 309

Below we illustrate and prove that 2 and 309 multiply to 618 and add up to 311:

2 × 309 = 618
2 + 309 = 311

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

x² + 311x + 618 = 0

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

(x + 2 ) (x + 309)

To summarize, since 2 and 309 multiply to 618 and add up 311, you know that the following is true:

x² + 311x + 618 = (x + 2 ) (x + 309)
