What two numbers multiply to -170 and add up to 169?

Here we answer the question: "What two numbers multiply to -170 and add up to 169?"

The answer to your question is:

-1 and 170

Below we illustrate and prove that -1 and 170 multiply to -170 and add up to 169:

-1 × 170 = -170
-1 + 170 = 169

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

x² + 169x - 170 = 0

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

(x - 1 ) (x + 170)

To summarize, since -1 and 170 multiply to -170 and add up 169, you know that the following is true:

x² + 169x - 170 = (x - 1 ) (x + 170)
