What two numbers multiply to -181 and add up to 180?

Here we answer the question: "What two numbers multiply to -181 and add up to 180?"

The answer to your question is:

-1 and 181

Below we illustrate and prove that -1 and 181 multiply to -181 and add up to 180:

-1 × 181 = -181
-1 + 181 = 180

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

x² + 180x - 181 = 0

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

(x - 1 ) (x + 181)

To summarize, since -1 and 181 multiply to -181 and add up 180, you know that the following is true:

x² + 180x - 181 = (x - 1 ) (x + 181)
