What two numbers multiply to 490 and add up to -247?

Here we answer the question: "What two numbers multiply to 490 and add up to -247?"

The answer to your question is:

-245 and -2

Below we illustrate and prove that -245 and -2 multiply to 490 and add up to -247:

-245 × -2 = 490
-245 + -2 = -247

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

x² - 247x + 490 = 0

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

(x - 245 ) (x - 2)

To summarize, since -245 and -2 multiply to 490 and add up -247, you know that the following is true:

x² - 247x + 490 = (x - 245 ) (x - 2)
