What two numbers multiply to -455 and add up to 86?

Here we answer the question: "What two numbers multiply to -455 and add up to 86?"

The answer to your question is:

-5 and 91

Below we illustrate and prove that -5 and 91 multiply to -455 and add up to 86:

-5 × 91 = -455
-5 + 91 = 86

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

x² + 86x - 455 = 0

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

(x - 5 ) (x + 91)

To summarize, since -5 and 91 multiply to -455 and add up 86, you know that the following is true:

x² + 86x - 455 = (x - 5 ) (x + 91)
