What two numbers multiply to -790 and add up to 789?

Here we answer the question: "What two numbers multiply to -790 and add up to 789?"

The answer to your question is:

-1 and 790

Below we illustrate and prove that -1 and 790 multiply to -790 and add up to 789:

-1 × 790 = -790
-1 + 790 = 789

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

x² + 789x - 790 = 0

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

(x - 1 ) (x + 790)

To summarize, since -1 and 790 multiply to -790 and add up 789, you know that the following is true:

x² + 789x - 790 = (x - 1 ) (x + 790)
