What two numbers multiply to -288 and add up to 42?




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

The answer to your question is:

-6 and 48


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

-6 × 48 = -288
-6 + 48 = 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 - 6 ) (x + 48)

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

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