What two numbers multiply to -913 and add up to 72?

Here we answer the question: "What two numbers multiply to -913 and add up to 72?"

The answer to your question is:

-11 and 83

Below we illustrate and prove that -11 and 83 multiply to -913 and add up to 72:

-11 × 83 = -913
-11 + 83 = 72

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

x² + 72x - 913 = 0

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

(x - 11 ) (x + 83)

To summarize, since -11 and 83 multiply to -913 and add up 72, you know that the following is true:

x² + 72x - 913 = (x - 11 ) (x + 83)
