What two numbers multiply to 646 and add up to 53?

Here we answer the question: "What two numbers multiply to 646 and add up to 53?"

The answer to your question is:

19 and 34

Below we illustrate and prove that 19 and 34 multiply to 646 and add up to 53:

19 × 34 = 646
19 + 34 = 53

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

x² + 53x + 646 = 0

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

(x + 19 ) (x + 34)

To summarize, since 19 and 34 multiply to 646 and add up 53, you know that the following is true:

x² + 53x + 646 = (x + 19 ) (x + 34)
