What two numbers multiply to 840 and add up to 173?

Here we answer the question: "What two numbers multiply to 840 and add up to 173?"

The answer to your question is:

5 and 168

Below we illustrate and prove that 5 and 168 multiply to 840 and add up to 173:

5 × 168 = 840
5 + 168 = 173

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

x² + 173x + 840 = 0

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

(x + 5 ) (x + 168)

To summarize, since 5 and 168 multiply to 840 and add up 173, you know that the following is true:

x² + 173x + 840 = (x + 5 ) (x + 168)
