What two numbers multiply to -284 and add up to 140?

Here we answer the question: "What two numbers multiply to -284 and add up to 140?"

The answer to your question is:

-2 and 142

Below we illustrate and prove that -2 and 142 multiply to -284 and add up to 140:

-2 × 142 = -284
-2 + 142 = 140

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

x² + 140x - 284 = 0

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

(x - 2 ) (x + 142)

To summarize, since -2 and 142 multiply to -284 and add up 140, you know that the following is true:

x² + 140x - 284 = (x - 2 ) (x + 142)
