What two numbers multiply to -873 and add up to 288?

Here we answer the question: "What two numbers multiply to -873 and add up to 288?"

The answer to your question is:

-3 and 291

Below we illustrate and prove that -3 and 291 multiply to -873 and add up to 288:

-3 × 291 = -873
-3 + 291 = 288

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

x² + 288x - 873 = 0

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

(x - 3 ) (x + 291)

To summarize, since -3 and 291 multiply to -873 and add up 288, you know that the following is true:

x² + 288x - 873 = (x - 3 ) (x + 291)
