What two numbers multiply to -870 and add up to -287?

Here we answer the question: "What two numbers multiply to -870 and add up to -287?"

The answer to your question is:

-290 and 3

Below we illustrate and prove that -290 and 3 multiply to -870 and add up to -287:

-290 × 3 = -870
-290 + 3 = -287

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

x² - 287x - 870 = 0

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

(x - 290 ) (x + 3)

To summarize, since -290 and 3 multiply to -870 and add up -287, you know that the following is true:

x² - 287x - 870 = (x - 290 ) (x + 3)
