What two numbers multiply to 30 and add up to -17?

Here we answer the question: "What two numbers multiply to 30 and add up to -17?"

The answer to your question is:

-15 and -2

Below we illustrate and prove that -15 and -2 multiply to 30 and add up to -17:

-15 × -2 = 30
-15 + -2 = -17

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

x² - 17x + 30 = 0

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

(x - 15 ) (x - 2)

To summarize, since -15 and -2 multiply to 30 and add up -17, you know that the following is true:

x² - 17x + 30 = (x - 15 ) (x - 2)
