What two numbers multiply to 560 and add up to -144?

Here we answer the question: "What two numbers multiply to 560 and add up to -144?"

The answer to your question is:

-140 and -4

Below we illustrate and prove that -140 and -4 multiply to 560 and add up to -144:

-140 × -4 = 560
-140 + -4 = -144

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

x² - 144x + 560 = 0

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

(x - 140 ) (x - 4)

To summarize, since -140 and -4 multiply to 560 and add up -144, you know that the following is true:

x² - 144x + 560 = (x - 140 ) (x - 4)
