Here we answer the question: "What two numbers multiply to 990 and add up to -497?"

The answer to your question is:

-495 and -2

Below we illustrate and prove that -495 and -2 multiply to 990 and add up to -497:

-495 × -2 = 990
-495 + -2 = -497

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

x² - 497x + 990 = 0

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

(x - 495 ) (x - 2)

To summarize, since -495 and -2 multiply to 990 and add up -497, you know that the following is true:

x² - 497x + 990 = (x - 495 ) (x - 2)
