What two numbers multiply to -770 and add up to 769?

Here we answer the question: "What two numbers multiply to -770 and add up to 769?"

The answer to your question is:

-1 and 770

Below we illustrate and prove that -1 and 770 multiply to -770 and add up to 769:

-1 × 770 = -770
-1 + 770 = 769

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

x² + 769x - 770 = 0

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

(x - 1 ) (x + 770)

To summarize, since -1 and 770 multiply to -770 and add up 769, you know that the following is true:

x² + 769x - 770 = (x - 1 ) (x + 770)
