What two numbers multiply to -649 and add up to 48?

Here we answer the question: "What two numbers multiply to -649 and add up to 48?"

The answer to your question is:

-11 and 59

Below we illustrate and prove that -11 and 59 multiply to -649 and add up to 48:

-11 × 59 = -649
-11 + 59 = 48

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

x² + 48x - 649 = 0

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

(x - 11 ) (x + 59)

To summarize, since -11 and 59 multiply to -649 and add up 48, you know that the following is true:

x² + 48x - 649 = (x - 11 ) (x + 59)
