What two numbers multiply to 479 and add up to 480?

Here we answer the question: "What two numbers multiply to 479 and add up to 480?"

The answer to your question is:

1 and 479

Below we illustrate and prove that 1 and 479 multiply to 479 and add up to 480:

1 × 479 = 479
1 + 479 = 480

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

x² + 480x + 479 = 0

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

(x + 1 ) (x + 479)

To summarize, since 1 and 479 multiply to 479 and add up 480, you know that the following is true:

x² + 480x + 479 = (x + 1 ) (x + 479)
