What two numbers multiply to 615 and add up to -56?

Here we answer the question: "What two numbers multiply to 615 and add up to -56?"

The answer to your question is:

-41 and -15

Below we illustrate and prove that -41 and -15 multiply to 615 and add up to -56:

-41 × -15 = 615
-41 + -15 = -56

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

x² - 56x + 615 = 0

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

(x - 41 ) (x - 15)

To summarize, since -41 and -15 multiply to 615 and add up -56, you know that the following is true:

x² - 56x + 615 = (x - 41 ) (x - 15)
