What two numbers multiply to 684 and add up to 69?

Here we answer the question: "What two numbers multiply to 684 and add up to 69?"

The answer to your question is:

12 and 57

Below we illustrate and prove that 12 and 57 multiply to 684 and add up to 69:

12 × 57 = 684
12 + 57 = 69

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

x² + 69x + 684 = 0

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

(x + 12 ) (x + 57)

To summarize, since 12 and 57 multiply to 684 and add up 69, you know that the following is true:

x² + 69x + 684 = (x + 12 ) (x + 57)
