What two numbers multiply to 280 and add up to 281?

Here we answer the question: "What two numbers multiply to 280 and add up to 281?"

The answer to your question is:

1 and 280

Below we illustrate and prove that 1 and 280 multiply to 280 and add up to 281:

1 × 280 = 280
1 + 280 = 281

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

x² + 281x + 280 = 0

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

(x + 1 ) (x + 280)

To summarize, since 1 and 280 multiply to 280 and add up 281, you know that the following is true:

x² + 281x + 280 = (x + 1 ) (x + 280)
