What two numbers multiply to -777 and add up to 776?

Here we answer the question: "What two numbers multiply to -777 and add up to 776?"

The answer to your question is:

-1 and 777

Below we illustrate and prove that -1 and 777 multiply to -777 and add up to 776:

-1 × 777 = -777
-1 + 777 = 776

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

x² + 776x - 777 = 0

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

(x - 1 ) (x + 777)

To summarize, since -1 and 777 multiply to -777 and add up 776, you know that the following is true:

x² + 776x - 777 = (x - 1 ) (x + 777)
