What two numbers multiply to 84 and add up to 20?

Here we answer the question: "What two numbers multiply to 84 and add up to 20?"

The answer to your question is:

6 and 14

Below we illustrate and prove that 6 and 14 multiply to 84 and add up to 20:

6 × 14 = 84
6 + 14 = 20

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

x² + 20x + 84 = 0

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

(x + 6 ) (x + 14)

To summarize, since 6 and 14 multiply to 84 and add up 20, you know that the following is true:

x² + 20x + 84 = (x + 6 ) (x + 14)
