What two numbers multiply to 840 and add up to 74?

Here we answer the question: "What two numbers multiply to 840 and add up to 74?"

The answer to your question is:

14 and 60

Below we illustrate and prove that 14 and 60 multiply to 840 and add up to 74:

14 × 60 = 840
14 + 60 = 74

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

x² + 74x + 840 = 0

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

(x + 14 ) (x + 60)

To summarize, since 14 and 60 multiply to 840 and add up 74, you know that the following is true:

x² + 74x + 840 = (x + 14 ) (x + 60)
