What two numbers multiply to 642 and add up to 113?

Here we answer the question: "What two numbers multiply to 642 and add up to 113?"

The answer to your question is:

6 and 107

Below we illustrate and prove that 6 and 107 multiply to 642 and add up to 113:

6 × 107 = 642
6 + 107 = 113

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

x² + 113x + 642 = 0

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

(x + 6 ) (x + 107)

To summarize, since 6 and 107 multiply to 642 and add up 113, you know that the following is true:

x² + 113x + 642 = (x + 6 ) (x + 107)
