Here we answer the question: "What two numbers multiply to -288 and add up to -42?"

The answer to your question is:

-48 and 6


Below we illustrate and prove that -48 and 6 multiply to -288 and add up to -42:

-48 × 6 = -288
-48 + 6 = -42

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

x2 - 42x - 288 = 0

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

(x - 48 ) (x + 6)

To summarize, since -48 and 6 multiply to -288 and add up -42, you know that the following is true:

x2 - 42x - 288 = (x - 48 ) (x + 6)
