What two numbers multiply to 489 and add up to 490?

Here we answer the question: "What two numbers multiply to 489 and add up to 490?"

The answer to your question is:

1 and 489

Below we illustrate and prove that 1 and 489 multiply to 489 and add up to 490:

1 × 489 = 489
1 + 489 = 490

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

x² + 490x + 489 = 0

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

(x + 1 ) (x + 489)

To summarize, since 1 and 489 multiply to 489 and add up 490, you know that the following is true:

x² + 490x + 489 = (x + 1 ) (x + 489)
