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:

-7 and 40

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

-7 × 40 = -280
-7 + 40 = 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 - 7 ) (x + 40)

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

x² + 33x - 280 = (x - 7 ) (x + 40)
