What two numbers multiply to -568 and add up to 138?

Here we answer the question: "What two numbers multiply to -568 and add up to 138?"

The answer to your question is:

-4 and 142

Below we illustrate and prove that -4 and 142 multiply to -568 and add up to 138:

-4 × 142 = -568
-4 + 142 = 138

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

x² + 138x - 568 = 0

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

(x - 4 ) (x + 142)

To summarize, since -4 and 142 multiply to -568 and add up 138, you know that the following is true:

x² + 138x - 568 = (x - 4 ) (x + 142)
