What two numbers multiply to -141 and add up to 140?

Here we answer the question: "What two numbers multiply to -141 and add up to 140?"

The answer to your question is:

-1 and 141

Below we illustrate and prove that -1 and 141 multiply to -141 and add up to 140:

-1 × 141 = -141
-1 + 141 = 140

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

x² + 140x - 141 = 0

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

(x - 1 ) (x + 141)

To summarize, since -1 and 141 multiply to -141 and add up 140, you know that the following is true:

x² + 140x - 141 = (x - 1 ) (x + 141)
