What two numbers multiply to 477 and add up to 478?

Here we answer the question: "What two numbers multiply to 477 and add up to 478?"

The answer to your question is:

1 and 477

Below we illustrate and prove that 1 and 477 multiply to 477 and add up to 478:

1 × 477 = 477
1 + 477 = 478

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

x² + 478x + 477 = 0

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

(x + 1 ) (x + 477)

To summarize, since 1 and 477 multiply to 477 and add up 478, you know that the following is true:

x² + 478x + 477 = (x + 1 ) (x + 477)
