What two numbers multiply to -340 and add up to 3?

Here we answer the question: "What two numbers multiply to -340 and add up to 3?"

The answer to your question is:

-17 and 20

Below we illustrate and prove that -17 and 20 multiply to -340 and add up to 3:

-17 × 20 = -340
-17 + 20 = 3

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

x² + 3x - 340 = 0

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

(x - 17 ) (x + 20)

To summarize, since -17 and 20 multiply to -340 and add up 3, you know that the following is true:

x² + 3x - 340 = (x - 17 ) (x + 20)
