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

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

The answer to your question is:

1 and 615

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

1 × 615 = 615
1 + 615 = 616

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

x² + 616x + 615 = 0

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

(x + 1 ) (x + 615)

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

x² + 616x + 615 = (x + 1 ) (x + 615)
