What two numbers multiply to 861 and add up to -290?

Here we answer the question: "What two numbers multiply to 861 and add up to -290?"

The answer to your question is:

-287 and -3

Below we illustrate and prove that -287 and -3 multiply to 861 and add up to -290:

-287 × -3 = 861
-287 + -3 = -290

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

x² - 290x + 861 = 0

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

(x - 287 ) (x - 3)

To summarize, since -287 and -3 multiply to 861 and add up -290, you know that the following is true:

x² - 290x + 861 = (x - 287 ) (x - 3)
