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:

2 and 15

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

2 × 15 = 30
2 + 15 = 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 + 2 ) (x + 15)

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

x² + 17x + 30 = (x + 2 ) (x + 15)
