What two numbers multiply to 280 and add up to -142?

Here we answer the question: "What two numbers multiply to 280 and add up to -142?"

The answer to your question is:

-140 and -2

Below we illustrate and prove that -140 and -2 multiply to 280 and add up to -142:

-140 × -2 = 280
-140 + -2 = -142

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

x² - 142x + 280 = 0

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

(x - 140 ) (x - 2)

To summarize, since -140 and -2 multiply to 280 and add up -142, you know that the following is true:

x² - 142x + 280 = (x - 140 ) (x - 2)
