What two numbers multiply to -790 and add up to 69?

Here we answer the question: "What two numbers multiply to -790 and add up to 69?"

The answer to your question is:

-10 and 79

Below we illustrate and prove that -10 and 79 multiply to -790 and add up to 69:

-10 × 79 = -790
-10 + 79 = 69

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

x² + 69x - 790 = 0

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

(x - 10 ) (x + 79)

To summarize, since -10 and 79 multiply to -790 and add up 69, you know that the following is true:

x² + 69x - 790 = (x - 10 ) (x + 79)
