What two numbers multiply to -490 and add up to -63?

Here we answer the question: "What two numbers multiply to -490 and add up to -63?"

The answer to your question is:

-70 and 7

Below we illustrate and prove that -70 and 7 multiply to -490 and add up to -63:

-70 × 7 = -490
-70 + 7 = -63

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

x² - 63x - 490 = 0

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

(x - 70 ) (x + 7)

To summarize, since -70 and 7 multiply to -490 and add up -63, you know that the following is true:

x² - 63x - 490 = (x - 70 ) (x + 7)
