What two numbers multiply to -342 and add up to 169?

Here we answer the question: "What two numbers multiply to -342 and add up to 169?"

The answer to your question is:

-2 and 171

Below we illustrate and prove that -2 and 171 multiply to -342 and add up to 169:

-2 × 171 = -342
-2 + 171 = 169

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

x² + 169x - 342 = 0

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

(x - 2 ) (x + 171)

To summarize, since -2 and 171 multiply to -342 and add up 169, you know that the following is true:

x² + 169x - 342 = (x - 2 ) (x + 171)
