What two numbers multiply to -340 and add up to 168?

Here we answer the question: "What two numbers multiply to -340 and add up to 168?"

The answer to your question is:

-2 and 170

Below we illustrate and prove that -2 and 170 multiply to -340 and add up to 168:

-2 × 170 = -340
-2 + 170 = 168

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

x² + 168x - 340 = 0

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

(x - 2 ) (x + 170)

To summarize, since -2 and 170 multiply to -340 and add up 168, you know that the following is true:

x² + 168x - 340 = (x - 2 ) (x + 170)
