What two numbers multiply to -160 and add up to 159?

Here we answer the question: "What two numbers multiply to -160 and add up to 159?"

The answer to your question is:

-1 and 160

Below we illustrate and prove that -1 and 160 multiply to -160 and add up to 159:

-1 × 160 = -160
-1 + 160 = 159

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

x² + 159x - 160 = 0

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

(x - 1 ) (x + 160)

To summarize, since -1 and 160 multiply to -160 and add up 159, you know that the following is true:

x² + 159x - 160 = (x - 1 ) (x + 160)
