What two numbers multiply to 855 and add up to 288?

Here we answer the question: "What two numbers multiply to 855 and add up to 288?"

The answer to your question is:

3 and 285

Below we illustrate and prove that 3 and 285 multiply to 855 and add up to 288:

3 × 285 = 855
3 + 285 = 288

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

x² + 288x + 855 = 0

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

(x + 3 ) (x + 285)

To summarize, since 3 and 285 multiply to 855 and add up 288, you know that the following is true:

x² + 288x + 855 = (x + 3 ) (x + 285)
