What two numbers multiply to 478 and add up to 479?

Here we answer the question: "What two numbers multiply to 478 and add up to 479?"

The answer to your question is:

1 and 478

Below we illustrate and prove that 1 and 478 multiply to 478 and add up to 479:

1 × 478 = 478
1 + 478 = 479

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

x² + 479x + 478 = 0

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

(x + 1 ) (x + 478)

To summarize, since 1 and 478 multiply to 478 and add up 479, you know that the following is true:

x² + 479x + 478 = (x + 1 ) (x + 478)
