What two numbers multiply to -171 and add up to 170?

Here we answer the question: "What two numbers multiply to -171 and add up to 170?"

The answer to your question is:

-1 and 171

Below we illustrate and prove that -1 and 171 multiply to -171 and add up to 170:

-1 × 171 = -171
-1 + 171 = 170

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

x² + 170x - 171 = 0

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

(x - 1 ) (x + 171)

To summarize, since -1 and 171 multiply to -171 and add up 170, you know that the following is true:

x² + 170x - 171 = (x - 1 ) (x + 171)
