What two numbers multiply to -360 and add up to 86?

Here we answer the question: "What two numbers multiply to -360 and add up to 86?"

The answer to your question is:

-4 and 90

Below we illustrate and prove that -4 and 90 multiply to -360 and add up to 86:

-4 × 90 = -360
-4 + 90 = 86

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

x² + 86x - 360 = 0

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

(x - 4 ) (x + 90)

To summarize, since -4 and 90 multiply to -360 and add up 86, you know that the following is true:

x² + 86x - 360 = (x - 4 ) (x + 90)
