What two numbers multiply to -161 and add up to 160?

Here we answer the question: "What two numbers multiply to -161 and add up to 160?"

The answer to your question is:

-1 and 161

Below we illustrate and prove that -1 and 161 multiply to -161 and add up to 160:

-1 × 161 = -161
-1 + 161 = 160

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

x² + 160x - 161 = 0

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

(x - 1 ) (x + 161)

To summarize, since -1 and 161 multiply to -161 and add up 160, you know that the following is true:

x² + 160x - 161 = (x - 1 ) (x + 161)
