What two numbers multiply to 30 and add up to 13?

Here we answer the question: "What two numbers multiply to 30 and add up to 13?"

The answer to your question is:

3 and 10

Below we illustrate and prove that 3 and 10 multiply to 30 and add up to 13:

3 × 10 = 30
3 + 10 = 13

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

x² + 13x + 30 = 0

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

(x + 3 ) (x + 10)

To summarize, since 3 and 10 multiply to 30 and add up 13, you know that the following is true:

x² + 13x + 30 = (x + 3 ) (x + 10)
