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:

-5 and 123

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

-5 × 123 = -615
-5 + 123 = 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 - 5 ) (x + 123)

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

x² + 118x - 615 = (x - 5 ) (x + 123)
