What two numbers multiply to -497 and add up to 64?

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

The answer to your question is:

-7 and 71

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

-7 × 71 = -497
-7 + 71 = 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 - 7 ) (x + 71)

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

x² + 64x - 497 = (x - 7 ) (x + 71)
