What two numbers multiply to -616 and add up to 615?

Here we answer the question: "What two numbers multiply to -616 and add up to 615?"

The answer to your question is:

-1 and 616

Below we illustrate and prove that -1 and 616 multiply to -616 and add up to 615:

-1 × 616 = -616
-1 + 616 = 615

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

x² + 615x - 616 = 0

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

(x - 1 ) (x + 616)

To summarize, since -1 and 616 multiply to -616 and add up 615, you know that the following is true:

x² + 615x - 616 = (x - 1 ) (x + 616)
