What two numbers multiply to 618 and add up to 209?

Here we answer the question: "What two numbers multiply to 618 and add up to 209?"

The answer to your question is:

3 and 206

Below we illustrate and prove that 3 and 206 multiply to 618 and add up to 209:

3 × 206 = 618
3 + 206 = 209

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

x² + 209x + 618 = 0

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

(x + 3 ) (x + 206)

To summarize, since 3 and 206 multiply to 618 and add up 209, you know that the following is true:

x² + 209x + 618 = (x + 3 ) (x + 206)
