What two numbers multiply to 168 and add up to 86?

Here we answer the question: "What two numbers multiply to 168 and add up to 86?"

The answer to your question is:

2 and 84

Below we illustrate and prove that 2 and 84 multiply to 168 and add up to 86:

2 × 84 = 168
2 + 84 = 86

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

x² + 86x + 168 = 0

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

(x + 2 ) (x + 84)

To summarize, since 2 and 84 multiply to 168 and add up 86, you know that the following is true:

x² + 86x + 168 = (x + 2 ) (x + 84)
