What two numbers multiply to -595 and add up to 78?

Here we answer the question: "What two numbers multiply to -595 and add up to 78?"

The answer to your question is:

-7 and 85

Below we illustrate and prove that -7 and 85 multiply to -595 and add up to 78:

-7 × 85 = -595
-7 + 85 = 78

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

x² + 78x - 595 = 0

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

(x - 7 ) (x + 85)

To summarize, since -7 and 85 multiply to -595 and add up 78, you know that the following is true:

x² + 78x - 595 = (x - 7 ) (x + 85)
