What two numbers multiply to -34 and add up to 15?

Here we answer the question: "What two numbers multiply to -34 and add up to 15?"

The answer to your question is:

-2 and 17

Below we illustrate and prove that -2 and 17 multiply to -34 and add up to 15:

-2 × 17 = -34
-2 + 17 = 15

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

x² + 15x - 34 = 0

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

(x - 2 ) (x + 17)

To summarize, since -2 and 17 multiply to -34 and add up 15, you know that the following is true:

x² + 15x - 34 = (x - 2 ) (x + 17)
