What two numbers multiply to -615 and add up to -118?

Here we answer the question: "What two numbers multiply to -615 and add up to -118?"

The answer to your question is:

-123 and 5

Below we illustrate and prove that -123 and 5 multiply to -615 and add up to -118:

-123 × 5 = -615
-123 + 5 = -118

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

x² - 118x - 615 = 0

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

(x - 123 ) (x + 5)

To summarize, since -123 and 5 multiply to -615 and add up -118, you know that the following is true:

x² - 118x - 615 = (x - 123 ) (x + 5)
