What two numbers multiply to -765 and add up to 76?

Here we answer the question: "What two numbers multiply to -765 and add up to 76?"

The answer to your question is:

-9 and 85

Below we illustrate and prove that -9 and 85 multiply to -765 and add up to 76:

-9 × 85 = -765
-9 + 85 = 76

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

x² + 76x - 765 = 0

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

(x - 9 ) (x + 85)

To summarize, since -9 and 85 multiply to -765 and add up 76, you know that the following is true:

x² + 76x - 765 = (x - 9 ) (x + 85)
