What two numbers multiply to -492 and add up to 491?

Here we answer the question: "What two numbers multiply to -492 and add up to 491?"

The answer to your question is:

-1 and 492

Below we illustrate and prove that -1 and 492 multiply to -492 and add up to 491:

-1 × 492 = -492
-1 + 492 = 491

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

x² + 491x - 492 = 0

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

(x - 1 ) (x + 492)

To summarize, since -1 and 492 multiply to -492 and add up 491, you know that the following is true:

x² + 491x - 492 = (x - 1 ) (x + 492)
