Here we answer the question: "What two numbers multiply to -497 and add up to -64?"

The answer to your question is:

-71 and 7

Below we illustrate and prove that -71 and 7 multiply to -497 and add up to -64:

-71 × 7 = -497
-71 + 7 = -64

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

x² - 64x - 497 = 0

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

(x - 71 ) (x + 7)

To summarize, since -71 and 7 multiply to -497 and add up -64, you know that the following is true:

x² - 64x - 497 = (x - 71 ) (x + 7)
