What two numbers multiply to 418 and add up to 419?

Here we answer the question: "What two numbers multiply to 418 and add up to 419?"

The answer to your question is:

1 and 418

Below we illustrate and prove that 1 and 418 multiply to 418 and add up to 419:

1 × 418 = 418
1 + 418 = 419

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

x² + 419x + 418 = 0

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

(x + 1 ) (x + 418)

To summarize, since 1 and 418 multiply to 418 and add up 419, you know that the following is true:

x² + 419x + 418 = (x + 1 ) (x + 418)
