What two numbers multiply to 490 and add up to 491?

Here we answer the question: "What two numbers multiply to 490 and add up to 491?"

The answer to your question is:

1 and 490

Below we illustrate and prove that 1 and 490 multiply to 490 and add up to 491:

1 × 490 = 490
1 + 490 = 491

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

x² + 491x + 490 = 0

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

(x + 1 ) (x + 490)

To summarize, since 1 and 490 multiply to 490 and add up 491, you know that the following is true:

x² + 491x + 490 = (x + 1 ) (x + 490)
