What two numbers multiply to 515 and add up to 516?

Here we answer the question: "What two numbers multiply to 515 and add up to 516?"

The answer to your question is:

1 and 515

Below we illustrate and prove that 1 and 515 multiply to 515 and add up to 516:

1 × 515 = 515
1 + 515 = 516

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

x² + 516x + 515 = 0

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

(x + 1 ) (x + 515)

To summarize, since 1 and 515 multiply to 515 and add up 516, you know that the following is true:

x² + 516x + 515 = (x + 1 ) (x + 515)
