What two numbers multiply to 815 and add up to 168?

Here we answer the question: "What two numbers multiply to 815 and add up to 168?"

The answer to your question is:

5 and 163

Below we illustrate and prove that 5 and 163 multiply to 815 and add up to 168:

5 × 163 = 815
5 + 163 = 168

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

x² + 168x + 815 = 0

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

(x + 5 ) (x + 163)

To summarize, since 5 and 163 multiply to 815 and add up 168, you know that the following is true:

x² + 168x + 815 = (x + 5 ) (x + 163)
