What two numbers multiply to -785 and add up to 784?

Here we answer the question: "What two numbers multiply to -785 and add up to 784?"

The answer to your question is:

-1 and 785

Below we illustrate and prove that -1 and 785 multiply to -785 and add up to 784:

-1 × 785 = -785
-1 + 785 = 784

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

x² + 784x - 785 = 0

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

(x - 1 ) (x + 785)

To summarize, since -1 and 785 multiply to -785 and add up 784, you know that the following is true:

x² + 784x - 785 = (x - 1 ) (x + 785)
