What two numbers multiply to 419 and add up to 420?

Here we answer the question: "What two numbers multiply to 419 and add up to 420?"

The answer to your question is:

1 and 419

Below we illustrate and prove that 1 and 419 multiply to 419 and add up to 420:

1 × 419 = 419
1 + 419 = 420

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

x² + 420x + 419 = 0

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

(x + 1 ) (x + 419)

To summarize, since 1 and 419 multiply to 419 and add up 420, you know that the following is true:

x² + 420x + 419 = (x + 1 ) (x + 419)
