What two numbers multiply to -879 and add up to 290?

Here we answer the question: "What two numbers multiply to -879 and add up to 290?"

The answer to your question is:

-3 and 293

Below we illustrate and prove that -3 and 293 multiply to -879 and add up to 290:

-3 × 293 = -879
-3 + 293 = 290

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

x² + 290x - 879 = 0

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

(x - 3 ) (x + 293)

To summarize, since -3 and 293 multiply to -879 and add up 290, you know that the following is true:

x² + 290x - 879 = (x - 3 ) (x + 293)
