What two numbers multiply to 280 and add up to -61?

Here we answer the question: "What two numbers multiply to 280 and add up to -61?"

The answer to your question is:

-56 and -5

Below we illustrate and prove that -56 and -5 multiply to 280 and add up to -61:

-56 × -5 = 280
-56 + -5 = -61

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

x² - 61x + 280 = 0

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

(x - 56 ) (x - 5)

To summarize, since -56 and -5 multiply to 280 and add up -61, you know that the following is true:

x² - 61x + 280 = (x - 56 ) (x - 5)
