What two numbers multiply to 140 and add up to -39?

Here we answer the question: "What two numbers multiply to 140 and add up to -39?"

The answer to your question is:

-35 and -4

Below we illustrate and prove that -35 and -4 multiply to 140 and add up to -39:

-35 × -4 = 140
-35 + -4 = -39

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

x² - 39x + 140 = 0

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

(x - 35 ) (x - 4)

To summarize, since -35 and -4 multiply to 140 and add up -39, you know that the following is true:

x² - 39x + 140 = (x - 35 ) (x - 4)
