What two numbers multiply to -426 and add up to 425?

Here we answer the question: "What two numbers multiply to -426 and add up to 425?"

The answer to your question is:

-1 and 426

Below we illustrate and prove that -1 and 426 multiply to -426 and add up to 425:

-1 × 426 = -426
-1 + 426 = 425

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

x² + 425x - 426 = 0

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

(x - 1 ) (x + 426)

To summarize, since -1 and 426 multiply to -426 and add up 425, you know that the following is true:

x² + 425x - 426 = (x - 1 ) (x + 426)
