What two numbers multiply to 42 and add up to -17?

Here we answer the question: "What two numbers multiply to 42 and add up to -17?"

The answer to your question is:

-14 and -3

Below we illustrate and prove that -14 and -3 multiply to 42 and add up to -17:

-14 × -3 = 42
-14 + -3 = -17

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

x² - 17x + 42 = 0

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

(x - 14 ) (x - 3)

To summarize, since -14 and -3 multiply to 42 and add up -17, you know that the following is true:

x² - 17x + 42 = (x - 14 ) (x - 3)
