What two numbers multiply to -288 and add up to 2?

Here we answer the question: "What two numbers multiply to -288 and add up to 2?"

The answer to your question is:

-16 and 18

Below we illustrate and prove that -16 and 18 multiply to -288 and add up to 2:

-16 × 18 = -288
-16 + 18 = 2

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

x² + 2x - 288 = 0

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

(x - 16 ) (x + 18)

To summarize, since -16 and 18 multiply to -288 and add up 2, you know that the following is true:

x² + 2x - 288 = (x - 16 ) (x + 18)
