What two numbers multiply to -540 and add up to 12?




Here we answer the question: "What two numbers multiply to -540 and add up to 12?"

The answer to your question is:

-18 and 30


Below we illustrate and prove that -18 and 30 multiply to -540 and add up to 12:

-18 × 30 = -540
-18 + 30 = 12

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

x2 + 12x - 540 = 0

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

(x - 18 ) (x + 30)

To summarize, since -18 and 30 multiply to -540 and add up 12, you know that the following is true:

x2 + 12x - 540 = (x - 18 ) (x + 30)
