What two numbers multiply to 9 and add up to 6?

Here we answer the question: "What two numbers multiply to 9 and add up to 6?"

The answer to your question is:

3 and 3

Below we illustrate and prove that 3 and 3 multiply to 9 and add up to 6:

3 × 3 = 9
3 + 3 = 6

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

x² + 6x + 9 = 0

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

(x + 3 ) (x + 3)

To summarize, since 3 and 3 multiply to 9 and add up 6, you know that the following is true:

x² + 6x + 9 = (x + 3 ) (x + 3)
