What two numbers multiply to 287 and add up to -288?

Here we answer the question: "What two numbers multiply to 287 and add up to -288?"

The answer to your question is:

-287 and -1

Below we illustrate and prove that -287 and -1 multiply to 287 and add up to -288:

-287 × -1 = 287
-287 + -1 = -288

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

x² - 288x + 287 = 0

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

(x - 287 ) (x - 1)

To summarize, since -287 and -1 multiply to 287 and add up -288, you know that the following is true:

x² - 288x + 287 = (x - 287 ) (x - 1)
