What two numbers multiply to 257 and add up to 258?

Here we answer the question: "What two numbers multiply to 257 and add up to 258?"

The answer to your question is:

1 and 257

Below we illustrate and prove that 1 and 257 multiply to 257 and add up to 258:

1 × 257 = 257
1 + 257 = 258

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

x² + 258x + 257 = 0

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

(x + 1 ) (x + 257)

To summarize, since 1 and 257 multiply to 257 and add up 258, you know that the following is true:

x² + 258x + 257 = (x + 1 ) (x + 257)
