What two numbers multiply to 455 and add up to 456?

Here we answer the question: "What two numbers multiply to 455 and add up to 456?"

The answer to your question is:

1 and 455

Below we illustrate and prove that 1 and 455 multiply to 455 and add up to 456:

1 × 455 = 455
1 + 455 = 456

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

x² + 456x + 455 = 0

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

(x + 1 ) (x + 455)

To summarize, since 1 and 455 multiply to 455 and add up 456, you know that the following is true:

x² + 456x + 455 = (x + 1 ) (x + 455)
