What two numbers multiply to -280 and add up to -33?

Here we answer the question: "What two numbers multiply to -280 and add up to -33?"

The answer to your question is:

-40 and 7

Below we illustrate and prove that -40 and 7 multiply to -280 and add up to -33:

-40 × 7 = -280
-40 + 7 = -33

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

x² - 33x - 280 = 0

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

(x - 40 ) (x + 7)

To summarize, since -40 and 7 multiply to -280 and add up -33, you know that the following is true:

x² - 33x - 280 = (x - 40 ) (x + 7)
