What two numbers multiply to -157 and add up to 156?

Here we answer the question: "What two numbers multiply to -157 and add up to 156?"

The answer to your question is:

-1 and 157

Below we illustrate and prove that -1 and 157 multiply to -157 and add up to 156:

-1 × 157 = -157
-1 + 157 = 156

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

x² + 156x - 157 = 0

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

(x - 1 ) (x + 157)

To summarize, since -1 and 157 multiply to -157 and add up 156, you know that the following is true:

x² + 156x - 157 = (x - 1 ) (x + 157)
