What two numbers multiply to -426 and add up to 139?

Here we answer the question: "What two numbers multiply to -426 and add up to 139?"

The answer to your question is:

-3 and 142

Below we illustrate and prove that -3 and 142 multiply to -426 and add up to 139:

-3 × 142 = -426
-3 + 142 = 139

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

x² + 139x - 426 = 0

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

(x - 3 ) (x + 142)

To summarize, since -3 and 142 multiply to -426 and add up 139, you know that the following is true:

x² + 139x - 426 = (x - 3 ) (x + 142)
