What two numbers multiply to -280 and add up to -66?

Here we answer the question: "What two numbers multiply to -280 and add up to -66?"

The answer to your question is:

-70 and 4

Below we illustrate and prove that -70 and 4 multiply to -280 and add up to -66:

-70 × 4 = -280
-70 + 4 = -66

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

x² - 66x - 280 = 0

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

(x - 70 ) (x + 4)

To summarize, since -70 and 4 multiply to -280 and add up -66, you know that the following is true:

x² - 66x - 280 = (x - 70 ) (x + 4)
