What two numbers multiply to -627 and add up to 626?

Here we answer the question: "What two numbers multiply to -627 and add up to 626?"

The answer to your question is:

-1 and 627

Below we illustrate and prove that -1 and 627 multiply to -627 and add up to 626:

-1 × 627 = -627
-1 + 627 = 626

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

x² + 626x - 627 = 0

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

(x - 1 ) (x + 627)

To summarize, since -1 and 627 multiply to -627 and add up 626, you know that the following is true:

x² + 626x - 627 = (x - 1 ) (x + 627)
