What two numbers multiply to 715 and add up to 68?

Here we answer the question: "What two numbers multiply to 715 and add up to 68?"

The answer to your question is:

13 and 55

Below we illustrate and prove that 13 and 55 multiply to 715 and add up to 68:

13 × 55 = 715
13 + 55 = 68

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

x² + 68x + 715 = 0

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

(x + 13 ) (x + 55)

To summarize, since 13 and 55 multiply to 715 and add up 68, you know that the following is true:

x² + 68x + 715 = (x + 13 ) (x + 55)
