What two numbers multiply to -140 and add up to -68?

Here we answer the question: "What two numbers multiply to -140 and add up to -68?"

The answer to your question is:

-70 and 2

Below we illustrate and prove that -70 and 2 multiply to -140 and add up to -68:

-70 × 2 = -140
-70 + 2 = -68

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

x² - 68x - 140 = 0

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

(x - 70 ) (x + 2)

To summarize, since -70 and 2 multiply to -140 and add up -68, you know that the following is true:

x² - 68x - 140 = (x - 70 ) (x + 2)
