What two numbers multiply to -630 and add up to -27?

Here we answer the question: "What two numbers multiply to -630 and add up to -27?"

The answer to your question is:

-42 and 15

Below we illustrate and prove that -42 and 15 multiply to -630 and add up to -27:

-42 × 15 = -630
-42 + 15 = -27

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

x² - 27x - 630 = 0

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

(x - 42 ) (x + 15)

To summarize, since -42 and 15 multiply to -630 and add up -27, you know that the following is true:

x² - 27x - 630 = (x - 42 ) (x + 15)
