What two numbers multiply to -180 and add up to 31?

Here we answer the question: "What two numbers multiply to -180 and add up to 31?"

The answer to your question is:

-5 and 36

Below we illustrate and prove that -5 and 36 multiply to -180 and add up to 31:

-5 × 36 = -180
-5 + 36 = 31

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

x² + 31x - 180 = 0

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

(x - 5 ) (x + 36)

To summarize, since -5 and 36 multiply to -180 and add up 31, you know that the following is true:

x² + 31x - 180 = (x - 5 ) (x + 36)
